When a girl is sucking on your wang, you pinch her nose so she can't breathe (when she's least expecting it of course--SURPRISE!!) and grab her head with your other hand. She continues to suck your wang with much gusto (with her nose pinched) until she almost gags to death and drools like the creature from Alien.
See above for an example of a Wanghai Surprise.
