When a girl has her period on a guys chest and leaves it to harden over night. The girl then takes cookie cutters and makes red, crusty cookies that she feeds to the guy.
Guy 1: Dude, what did you and that hooker do last night?
Guy 2: Ugh man it was amazing! We made cookies and shit!
Guy 1: DUDE! SHE DID THAT TO YOU! WAIT! YOU ATE ONE!
Guy 2: Damn straight! I felt like the fuckin' Keebler Elf.
