St. Valentine's Day Massacre

Have some girls get on their knees in a line. Proceed to take your pants off and bunny hop down the line, slapping the girls across the cheek with your cock.

Girls get down, I am about to perform the St. Valentine's Day Massacre

St Valentine's Day Massacre

(Referencing Al Capone's Valentine's Day Massacre of 1929)

When you break up with your girlfriend on St Valentine's Day.

If you are not a misogynistic son of a bastard do not commit a St Valentine's Day Massacre on your girlfriend.
