The Italian Four Knights Jerome Gambit, also reached by 1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+ Kxf7 5.Nc3 Nf6.
Play usually develops slower than in the main line Jerome.

12...h6 13. Bh4 Ng4 14.Qg3 Nf6
Interestingly enough, even though Black has a piece for a pawn, after this move Stockfish 8 sees the position as even. Instead, it recommends the messy line 14...g5 15.Bxg5 hxg5 16.f5 Nge5 17.fxe6+ Kxe6 18.Rhf1 g4 19.Rf5 Rxf5 20.exf5+ Kd7 21.Ne4 b6 22.h3 gxh3 23.Qxh3 Qh8 24.Rh1 Qxh3 25.Nf6+ Kc8 26.Rxh3 Kb7 when Black has castled-by-hand on the Queenside and is clearly better - but I don't see two club players finding their way through all of that.
Thematic, but possibly premature. The computer prefers 15.Qe3 Kg8 with equality.
15...Nh5 16.Qf2 Qd7 17.h3 Rg8
This looks like a mouse-slip, instead of the better 17...Kg8, but I am not sure. Perhaps Black is planning on expanding on the Kingside, but he never gets the chance.
The King senses danger, and he is right.
19.gxh5 Bxh3 20.e6
A sacrifice to open the e-file, but the simple 20.exd6 was good enough.
20...Bxe6 21.Rhe1 Rf8
White has too much fire power on the files.
A final slip.
Black forfeited by disconnection, no doubt out of frustration at his last move; but the game was lost, for example 22...Qf7 23.Rxe6+ Qxe6 24.fxe6 Rxf2 25.Bxf2 when White has an extra piece and his advanced passed pawn will cause problems for Black.
