The deadliest trap
So, this is the budapest gambit most popular trap.
it starts with
1. d4 nf6
2. c4 e5
trying to sacrifice the e pawn to attack it back and win it later
3. dxe5 ng4
trying to attach the e pawn back
4. bf4 nc6
bf4 protects the pawn whilst nc6 attacks it again
5. nc3 bb5+
nc3 protects the pawn once again and bb5+ forces the other knight to come out otherwise the will lose the pawn (white will lose the pawn and black will be up the exchange)
6. nbd2 qe7
qe7 again attacks the pawn
7. a3 nxe5!!

8. axb5?? nd3#
