Many people play the Jerome Gambit for a very simple, straight-forward reason: it is fun. Imagine how much enjoyment Bill experienced in the following game, where he delivers wreckage and ruin upon the enemy King.

7...d6 8.Qd5+
Ah, "Nudge 2.0", another Wall specialty.
8...Ke7
Or 8...Ke8 as in Wall,B - Seven11, Chess.com, 2008 (1-0, 51)
Or 8...Kf8 as in Wall,B - Chung,J, Chess.com 2010 (1-0, 25).
Or 8...Be6 as in Wall, B - CheckMe, Chess.com, 2010 (1-0, 23) and Wall,B - Guest249301,PlayChess.com, 2013 (1-0, 30).
9.O-O
Or 9.d3 as in Wall,B - Guest4395, Internet, 2001 (1-0, 18).
9... Nf6
10.Qg5 Be6
Despite the awkward placement of his King, Black is feeling comfortable with his lead in development. All he has to do is take care of that pesky White Queen, and it will be smooth sailing, he reassures himself.
11.f4 Bf7 12.d4
Indeed, and how can White expect to prevail when he is only moving his Queen and his pawns? (Ah, the eternal Jerome Gambit question!)
12...h6 13.Qg3
Bill suggests 13.Qb5 and 13.Qf5 as alternate possibilities.
13...Re8
It looks risky for Black, but Bill's suggestion of 13...Nxe4 14.Qe1 d5 15.f5 Nf8 has merit.
14.f5 Nf8
This position reminds me of the kind of thing that my old "Chess Challenger 7" computer used to do - leave its King in the center of the board, surround it by pieces, and consider the position to be good. Often it would continue with the advance of a Rook pawn.
15.e5
Of course, Bill advances his "Jerome pawns" and plans to open up the center to get at the enemy King.
15...dxe5
Things are already dire for the defender, as Bill points out: 15...Nh5 16.Qh4+ Nf6 17.Bxh6 and 15...Nd5 16.Qxg7.
16.dxe5 Nd5
Or, fast and furious, any of the following: 16...Nh5 17.Qa3+ Kd7 18.Rd1+ or 16...Qd4+ 17.Be3 or 16...Ne4 17.Qh4+ Kd7 18.Qxe4.
17.Qxg7 Nd7 18.e6
18...N7f6 19.exf7 Rf8 20.Re1+ Kd6
21.c4 Nb6 22.Rd1+ Kc5 23.Rxd8 Raxd8 24.Be3+
As the loss of Black's Queen is not enough to cause him to strike his colors, Bill brings out some more pieces to enforce checkmate. Bill also notes that 24.Qxf6 leads to mate as well.
24...Kxc4 25.Na3+ Kd3 26.Bxh6 Ne4 27. Rd1+ Ke2 28. Qg4 checkmate
The watchwords of Aaron Nimzowitsch (1886-1935) "restrain, blockade, destroy" come to mind in playing over the following game, as Black seems to utilize "hypermodern" concepts in has battle against a clearly "neo-romantic" chess opening.
It is one of the stranger Jerome Gambits I have ever seen.
Wall, Bill - Guest4149739
PlayChess.com, 2013
1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+
4...Kxf7 5.Nxe5+ Nxe5 6.Qh5+ Ng6
7.Qd5+ Kf8
More common is 7...Ke8.
8.Qxc5+ d6
There is also 8...Qe7, as in Wall,B - Quack, Chess.com, 2010 (1-0, 22)
9.Qc3
The more-often played 9.Qe3 is as old as Vazquez,A -Carrington,W, Mexico, 2nd match, 1876 (1-0, 34) and as new as Wall,B - Vijay,V, Chess.com 2010 (1-0, 22) and Wall,B - LC, Chess.com, 2010 (1-0, 20)
9...Nf6 10.d3 Qe7
A slight improvement over 10...c6 as in Wall,B - Boris, Sparkchess.com, 2012 (1-0, 32). So far, we have a normal Jerome Gambit-style position.
11.O-O c6 12.f4 Bd7 13.f5 Ne5 14.h3
Bill later suggested 14.Bf4.
14...c5 15.g4 Bc6
White has activated his "Jerome pawns" and in response Black has started to restrain them and - with his Knights - blockade them.
An indication of how further "odd" the position can get is in Houdini's recommendation, instead of Black's last move: 15...g5 16.Bxg5 h5 17.h4 hxg4 18.a4 Be8 19.Nd2 Bf7.
16.g5 Nfd7 17.b4 h6 18.g6 Qh4
Black has about had it with all of White's pawn moves (Bill has also created this impatience in his opponents with repeated Queen moves) and decides to become aggressive, here threatening 19...Qg3+.
19.Kh2 b6 20.a4
Instead, 20.Bf4 was a possibility.
20...Nf6 21.Bf4
Bill shows how things could go horribly wrong for White: 21.bxc5? Nd5 22.exd5 Ng4+ 23.Kg2 Bxd5+ 24. Kg1 Qg3 checkmate
21...Re8
22.Nd2 Nh5 23.Bxe5 Rxe5
Threatening 24.. .Qg3+.
24.Rf3
White's King is still at risk: 24.bxc5? Qg3+ 25.Kh1 Rxe4 26.dxe4 (26.Nxe4 Bxe4+ 27.dxe4 Qxc3) 26...Qxc3.
24...Ke7 25.Rg1
White completes his development (!) and sets an interesting trap for his opponent.
25...Bxa4
This can lead to a slight advantage for White (better was 25...Kd7), or a whole lot more.
26.Ra1 b5
Black protects his Bishop and blocks the a-file against the White Rook. Instead, he should have retreated his piece with 26...Bd7 and let the White Rook in, facing a small disadvantage. However, this was far from obvious.
27.d4
With this move White takes over the game.
27...cxd4 28.Qc7+ Kf6
This leads to checkmate, whereas 28...Ke8 only leads to disaster after 29.Qc6+
29.Qxd6+
A bit faster was 29.Rg1
29...Kg5 30.Rg1+ Black resigned
It is ironic that Black, ahead in development for most of the game, should have his King expire with a Bishop offside and a Rook lollygagging at home.
Many people have an "anger management" problem of a specific kind: they put up with repeated small intrusions in their lives, saying nothing and setting no limits. Then, finally, the explode all out of proportion.
Wall,B - Guest3797656
Playchess.com, 2013
1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+
4...Kxf7 5.Nxe5+ Nxe5 6.Qh5+ Ng6
7.Qd5+ Kf8 8.Qxc5+ Qe7 9.Qe3 Nf6 10.Nc3 Kf7
Black is looking to castle-by-hand.
Previously seen: 10...c6 11.0-0 d5 12.f3 Qe5 13.d4 Qd6 14.e5 Qe6 15.exf6 Qxe3+ 16.Bxe3 gxf6 17.Bh6+ Kf7 18.Rae1 Re8 19.Rxe8 Kxe8 20.Re1+ Kf7 21.g4 Be6 22.Ne2 Black resigned, Wall,B - Quack, Chess.com, 2010.
11.0-0 Re8 12.f4 Kg8 13.d4 d5 14.f5 Nh8
Black has allowed White's "Jerome pawns" to swarm, bypassing ...Nxe4 several times. Soon he will strike back, but it will be poorly matched to the position.
15.e5 Ng4 16.Qd3 c6 17.h3 Nxe5 18.dxe5 Qxe5
The "science" is probably good here, as Black has returned his extra piece for two pawns, but he hardly has the advantage that he had at, say, moves 4, 6 or 8.
19.g4 d4
Again, Black "fights fire with fire," or aggression with aggression, but only after he has allowed White to bottle up his Bishop and Knight, which should have been attended to instead. Another explosion is building up.
20.Bf4 Qc5 21.Na4 Qb4 22.b3 b5 23.a3 Qe7 24.Rae1 Qxe1 25.Rxe1 Rxe1+ 26.Kf2 Re8 27.Nc5 Nf7
Black has aggressively exchanged his Queen for two Rooks, and achieved - what? White's pieces (including his King) are better developed and more prepared to swing into action.
28.g5 a5 29.f6 g6 30.h4 Bf5 31.Qxd4 Rad8
Finally. I still think White has the better game, however.
32.Qc3 Bg4 33.Qxa5 Re2+ 34.Kg3 Bf5
Again, passively allowing White's King to intrude, when 34...Rxc2 35.Kxg4 Rxc5 was the assertive way to go.
35.c3 Rd5 36.Qa8+ Nd8 37.Qb8 Rc2 38.Be5 Re2 39.Bd6 Re8
After making "scary" threats on the Queenside, Black's Rook returns to defense.
40.Be7
Threatening 41.Bxd8 Rdxd8 42.Qc7 and 43.Qg7 mate.
Black resigned.
