when a man wheres crimson socks in honor of the boston red sox and after having sex with his girlfriend who hasn't recently washed her vagina (therefore the "fish") takes his dick and smacks her repeatedly in the face with his penis.

Randy: hahaha awesome. by the way r u coming over to my house to watch the sox game???
