Dirty Jeff 

Lying on one's back while a female sits on your face. Oral sex is then performed on her. The key is to be a black belt in tongue fu. Her secretions then become heavier and heavier until they fill your lungs causing asphyxiation

After a long night of the Dirty Jeff, I am having problems breathing, but my girlfriend is very happy.
