The Stuka 

A sexual act whereby someone will run past their partner, who is laid on the floor, squat down at the last minute, and shit on their partner at the lowest part of the 'dive'. The sound effect of "NYEOOW" is not optional

"I met up with the Stuka Squadron the other night, it was a real mess. John got an absolute eyeful"
