commodo dragon 

when you grab the back of a girls head and hold it down while geting oral sex so that your load comes out of her nose.

you may or may not lose your freindship with the girl depending on how drunk or freaky she is.

stephanie was so pissed when i gave her the commodo dragon she hasnt talked to me for weeks

Commodo Dragon 

A large and smelly poo

Roommate #1: Dude, what was up with your GF this morning?
Roommate #2: She went to the bathroom and found that Commodo Dragon that you forgot to flush!
