NN - Philidor1792
1.e4 e5 2.Nf3 Bc5
The Busch-Gass Gambit. In some cases it envisions a reversed Jerome Gambit. See "Worth a Second Look... "Part 1, Part 2 and Part 3 and "The Busch-Gass Gambit".
Chiodini's Gambit. Black wishes to play a reversed Boden-Kieseritzky Gambit.
White sacrifices first!
I referred to this move in an earlier post as "a light-hearted alternative" to 4...Qf6. For that move, see Ake - Evilone, ICC, 1998 (0-1, 24) and hitorkoal - Philidor1792, Chess.com, 2015 (0-1, 71).
Not 5.Bc4 Qxf2 checkmate, Nguyen Bao Do - Dich Tai Khuu, VIE-ch, U07, 2014.

Is this strange enough for you?
White would do better to capture Black's Bishop at c5 rather than protect his Knight at h8. Bad things now happen.
