aquaqueef
A gush of water escaping from the vaginal opening, following sex in a water filled environment, spreading the vulva like the parting of the Red Sea. It is typically accompanied by the dreaded "wet fart" sound, and the always mortifying "wet crotch" look.
After doggie style shower sex with her husband, Kristy was talking with her father in law when a thunderous aquaqueef filled his ears, and her underwear.
Aquaqueef
When a vagina is so loose that when you go swimming and she gets out, it's like a queef with water coming out
I went to the pool today, and this lady had the biggest aquaqueef
