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.

Get the A-F-R-Omug. Piece of shit electronics purchase that is brand named to a big box store
In the 1980's you came home from school and your Dad burst into excitement as he boasted to you about his most recent electronics purchase for the family vehicle, he throws you the keys and you race to the car to see, as you run with great joy you imagine how great the new Alpine/Pioneer/Blaupunkt sound system will sound and how cool your friends are going to think you are. You open the rotted out door on your dads k-car only to find a Canadian Tire brand Spark-O-Matic radio looking back at you, to compare, if this radio were a pair of jeans it would have been a designer pair from the salvation army. So when someone you know purchases a Big Box store brand electronics item you call it "Spark-O-Matic".
