polynesian volcano 

A polynesian volcano is when you empty a bag of pop rocks in a gaping asshole, then pour a can of coke in and hurry and shove your dick in and hold it there until her ass explodes like a polynesian volcano.

Jesus, Mike D totally pulled off a polynesian volcano on that towney broad last night! #benaffleck
