Smoochie Daddy
When a really horny girl gets off by collecting the sweat from a fat man's folds into a cup, before proceeding to drink it in a sexual fashion. Can also be done vice-versa, although this would be called a "Smoochie Mommy".
Brittany: Hey Pete, can I perform a Smoochie Daddy on you? Pete: Sure Brittany, let me just lift up my shirt first. Brittany(After collecting and drinking the sweat): Mmm, tastes just like last week's. Pete: Well, why wouldn't it? I only ever shower once a year.
