This is the start of the dubious but very tricky Alien Gambit, invented by a chess streamer under the alias Witty Alien. It is an aggressive move that challenges the e6, h7, and most notably the f7 square. In this gambit, if Black tries to kick the knight away with h6, White follows up with the move Nxf7??, forking the queen and the rook immediately, with potential light-square weaknesses near Black's king.

The Alien Gambit is dubious and can be punished; however, it is incredibly tricky due to Black having several light-squared holes on their kingside, enabling White's pieces to coordinate on those light squares and go for checkmate.
