look up any word, like sapiosexual:

1 definition by Tristram S

1: The act slapping someone with ones flaccid penis; usually, though not always across the face. The optimal jimmy slap leaves a damp, phallic shaped mark where the phallus made contact with its victim, though this is not mandatory.
Alex passed out at the party so John jimmy slapped him and took a Polaroid.
