1. Harder than hardcore

Pac-Man Jones made it rain at the strip club last night. It was the most gullycore thing I've ever seen.

gullyhole 

the most gloriously glorious of all screw holes on your partner's body, namely a vagina for girls, can be the arsehole in certain situations however.

"dude... her gullyhole was so effing tight... i thought i was going to spooge my pants just seeing it."

Gullyworks 

A somewhat pejorative term used generally to refer to a woman's primary reproductive organs.

(Typically used by men uncomfortable and/or unfamiliar with the female anatomy, often for comic effect.)

Bro 1: I can't watch the game bro. My girlfriend has an appointment with her gynecologist today and I have to pick her up from the office.

Bro 2: Bummer dude. Is she OK? What's the problem?

Bro 1: Not sure man. All I know is that something's wrong up there in the gullyworks. I don't really want to think about it.

::Both shudder uncomfortably and take a drink::
