Gwank

*The general word for a disgusting act of hardcore sex, but usually includes: sodomy(with various household items), choking, fighting while having sex, anal, oral, anal to oral, ass licking, etc.

**However the word gwank can simply be used by anyone wishing to put an intensly gross image in the listeners head without exactly knowing what the definition was!

*Although the woman screamed and said "stop filming!", the porn star continued to Gwank the unholy shit out of her vagina with that plunger

**hank "you see that old bitch?
jeff "yeah man"
hank " man would i like to gwank the fuck out of that bitch"
jeff " dude gross i dont want to think about that man."
