Rumplestilts Simpson 

A sexual act that typically involved one man and one woman, although it is designed to be flexible in that manner.

One person will lock the other inside of a crate until they recite the cum guzzler's creed (Usually Adlibbed due to lack of established creed). Upon release, the person will attmept to bite the other person's penis if one is present.

This will result in an unpleaseant time.

My girlfriend pulled a Rumplestilts Simpson on me last night. I had to go to the ER!

Noun: a moron, somebody with questionable mental ability. To be a rumpert is to act or speak with intense idiocy and daftness.
