When you fuck a chick in the ass (preferebly a butterface or an ugly chick? and then cut off her head to hide the evidence...excellent if you dont want anyone to know you fucked an ugly
Fred- "ah man i saw this chick at the bar and she had a kick ass body but i later found she was a butterface so i pulled a cape cod gillotine and nobody knew"

Frank-"wow dude i never woulda known if you didnt tell me just now"
