Fourth Wheel

The fourth wheel's job is to make sure the third wheel doesn't step his boundaries as a third wheel.

Girl: Hey, I've noticed that John has trying to cheat with me lately. Should we invite Henry to fourth wheel for us?

Boy: Yeah, I think John stepped his boundaries. Ill call Henry now.

The Fourth Theory

The Fourth Theory states that if there is a Third Theory, then the fourth series applies to the "other."

"While you may be talking about the third theory I'm already talking about the fourth theory, try and keep up."

Fantastic Fourgy

When there is a tight group of friends consisting of 2 guys and 2 girls who would probably end up having a foursome. Differing from the Fantastic 4 because there are 2 girls instead of 1, and 2 guys instead of 3. Standard foursome rules apply:

1: Guys can't make eye contact

2: Guys can't make bodily contact
*Exception*: High fives are acceptable

Person 1: "They're always together, I bet they're a Fantastic Fourgy"

Person 2: "We should form our own Fantastic Fourgy, and fight crime and stuff"

fourth eye

The section of the anus that cannot be seen without special night vision goggles that can see through the thick haze of feces. Excessive ass pounding can also open up the anus far enough to see the fourth eye.

Dawg 1: Dude I saw my Mom's fourth eye last night.

Dawg 2: Me too. I always beat off to your Mom through the bedroom window.
