to finger a virgin vagina or anus. like popping a cherry
, but with a finger.
to finger pop with more than one finger is also acceptable.
"it was my birthday, so the stewardess gave me a finger popping."
"i finger popped that bitch but she was like, damn, if you're just gonna stop there... so i fucked the shit outta her."
the sound made when one pulls out a finger from a vagina or anus
after i got done finger fucking her, that pussy went POP!
