San Diego chimney 

The sexual act in where the male smokes a cigarette, cigar, ect. and uses the females vagina as an ash tray until the object being smoked is completely gone. With the ashes still in the females vagina, the male fucks her as hard as he possibly can.

Guilanna got pissed last night because her pussy got burnt when we were doing the San Diego chimney.
