When a man puts a frozen brat in a woman's ass, waits until it thaws and then has her shit it out onto a bun. He then squirts mustard into her vagina and has her squirt it onto the brat. He then feeds it to her with his feet.
Guy 1: I gave Kelly the Frankfurt surprise last night.
Guy 2: Did you use mustard or relish?
Guy 1: Mustard.
