When a girl is having her period and is using a tampon, you go down on her and suck the tampon out of her vagina. It then becomes a Reverse Vac-O-Vag if you shoot the tampon back into her mouth when you kiss her.
Greg: Dude, Sarah was having her period so I tried to Vac-O-Vag her.
Nick: That's awesome, did you do a Reverse Vac-O-Vag?
Greg: Well, she wasn't actually using a tampon, so the blood just kinda went into my mouth...
Nick: Dude that's gross.
Greg: I fucking loved it!
Nick: We're not friends anymore. Sorry.
