One way for Black to make the Jerome Gambit "playable" is to give up tempos without gaining much in return. Bit by bit, White gets more compensation for his sacrificed material, until he has the better game.

7.Qd5+ Ke8 8.Qxc5 d6 9.Qe3 Nf6
10.O-O Kf7 11.f4 Re8
Stronger than the superficially attractive 11...Ng4, as in angelcamina - frn000,1 0 bullet, lichess.org, 2019 (1-0, 23)
12.Nc3
angelcamina has also played 12.d3, in angelcamina - Danielpia, 1-0, bullet, lichess.org, 2019 (1-0, 28)
12...Kg8 13.d4 Ng4 14.Qg3 Nf6
15.f5 Ne7 16.Bg5 Nc6 17.Bh6
This works, but more solid was 17.Rd1.
17...Nh5
This will not turn out well.
18.Qg4 Qf6 19.Qxh5 gxh6 20.Qxe8+ Qf8 21.Qxf8+ Kxf8
White is up the exchange and a couple of pawns. He has only to be careful about the clock.
22.Rad1 Nb4 23.Rd2 Nc6 24.a3 Bd7 25.Nd5 Rc8 26.Re1 a5 27.g4 a4

White's "Jerome pawns" would win the day, in any case.
The following bullet game is delightfully misleading. Black appears to be taking advantage of the open h-file, putting together a checkmating attack along it. Then, White goes and checkmates him.
Yes, the Jerome Gambit and bullet chess are like that.

4...Kxf7 5.Nxe5+ Nxe5 6.Qh5+ Ng6 7.Qd5+ Ke8 8.Qxc5 d6 9.Qe3 Nf6
So far, so routine.
10.O-O Kf7 11.f4 Ng4
Always the temptation to harass the Queen.
12.Qg3 h5
Even moreso.
13.h3 Be6
A daring offer of a piece, but he has an extra one. Or, is he offering two pieces? That can be risky, even in bullet.
14.f5 Bd7 15.fxg6+ Kxg6 16.hxg4 hxg4
17.Nc3 Qe7 18.d4 Rh7 19.e5 Rah8
And now there is a forced checkmate - but White delivers it.
20.Qd3+ Kh5 21.g3 g5 22.Kg2 Rf8 23.Rh1 checkmate
Wonderful!
