Quad-Digit

To insert four fingers into the vagina.

Last night I hooked up with some skank in my car... totally quad-digited her with no problem.

quad f'er

A rare beast- a female freak feet feaster aka a toe-sucking girl who is into worshipping male sweaty, smelly barefeet and sniffing guy's rank socks and sneakers.

I had some of the guys over the other night to watch the game. One dude brought a girl who turned out to be a quad f'er. She practically tackled me to take off my shoes and socks! By the end of the game, she had licked all our bare feet and sucked our toes.
