I'm a cheating piss ant.
I'm too fucking stupid to think of a rational way to capture your piece, so I'll pretend my pawn can move in a way it can't That's en passant.

A French chess term, which describes a special pawn move made to take the pawn of the opponent "passing by".
After his opponent moved his pawn from c7 to c5, he took it moving his pawn on d5 to c6, so this move was "en passant".
