A significant part of the Jerome Gambit box of tactics is the often vulnerable enemy Bishop on c5 - a proper Queen check by White, and the next move (or the one after) it can fall.
In the following game, Bill Wall waits - and waits - and waits for a Jerome, finally sacrificing his Bishop, anyway. Black never develops his dark-squared Bishop, but he drops a piece to a Queen check, any way.

1.e4 e5 2.Nf3 Nc6 3.Bc4 h6
The Semi-Italian Opening.
4.O-O a6 5.Nc3 b5
It is not a Jerome Gambit proper, but this is enough provocation.
6.Bxf7+ Kxf7 7.Nxe5+ Nxe5 8.Qh5+ Ng6 9.Qd5+
A different kind of "nudge".
9...Ke8 10.Qxa8 c6 11.d4 N8e7 12.f4 Kf7
Preparing to castle-by-hand? If so, it is untimely.
13.f5 Nh4 14.g3
Black resigned
White commands his not-quite-a-Jerome-gambit with skill, until his attention wavers - and his game disintegrates. Eyes on the prize, folks!

1.e4 e5 2.Nf3 Nc6 3.Bc4 h6
The Semi-Italian opening.
4.Nc3 Nf6 5.Bxf7+
White gives up waiting - if he was, indeed, waiting at all - for Black to play ...Bc5, and fires off his Bishop. An ounce more of patience was to be found in 5.0-0.
5...Kxf7 6.d4 exd4 7.Nxd4 Bb4 8.O-O Bxc3 9.bxc3 Nxd4 10.cxd4 d6
Here we have a Jerome-like position, with Black (with the less safe King) holding an extra piece, and White (with the better pawn center) holding an extra pawn. The gambiteer must attack fearlessly.
11.Qf3 Bg4 12.Qf4 g5 13.Qg3 Be6 14.e5
dxe5 15.dxe5 Nh5 16.Qf3+ Kg7
Black has systematically exchanged pieces, and then harassed White's Queen. This last move, however, looks like a mouse slip, as the alternative, 16...Kg6 would have protected the offside Knight.
17.Qxh5 Rf8
The second player's loose castling-by-hand gives his opponent the correct idea: attack the pawn at g5 with a pawn; exchange to open lines.
18.f4
This is the right idea, however, with the wrong pawn. What White should have been looking for is 18.h4, and even after 18...Qe8 19.Qxe8 Raxe8 20.hxg5 he would be clearly better.
18...Qd4+
Didn't see that coming.
19.Kh1 Qxa1 20.fxg5
So there!
20...Rxf1 checkmate
Speaking of "Discouragement", I have to report that the second round of the Chess.com "Italian Game" tournament has started (two sections, one with 6 players, one with 7) and I have 4 games with the black pieces, 2 games with the white pieces - and no Jerome Gambits.
At least, not yet.
Not every one of my opponents in this round will defend with the Two Knights, will they??
I hope not.
In the meantime, some things to think about: "Jerome Gambit vs Two Knights Defense (Part 1), (Part 2), (Part 3) and (Part 4)".
