Monster mash

Unprotected sex on Halloween necessitating an abortion, or a "graveyard smash"

Bro #1: Did you see that girl in the slutty giraffe costume?

Bro #2: Yeah, we monster mashed!

Bro #1: Nice! Better graveyard smash soon.

Bro #2: Yeah. We have an appointment after the new year.

Bro #1: Dude, that's too long. Haven't you heard about the heartbeat bill? You'd better get in there soon and get that baby!
