A crotch muppet is a strange animal that can occur when you don't wash your crotch enough...The animal will look a lot like the muppets and will have a strange voice- they are very hard to get rid of...

Harry: Hmmm; maybe you should try calling the exterminators. They could get on your girlfriend and try to get in her pants!
Bob: Wow yeah i should. Dayumm that would suck..
"She left her little crotch bomb at her mothers house so she could go out, get drunk and pull a train on those guys who were in town for the NASCAR race."
Crotch butter is indeed butter of the crotch. Meaning when you rub butter on your crotch, it becomes crotch butter. If you take off your underwear and smell popcorn butter, you call it...Crotch Butter.
