My friend Dan turned into a Holla Monster last night at the bar. I understand he hasn't had a date in a long time, but he literally tried to hit on every hot woman he came across.

The excuse you should ALWAYS give to your girlfriend when she bitches to you about grabbing/slapping her ass.
Zach: (slowly reaches for a game of grab-ass)
Kim: What the fuck, Zach! We're in public!
Zach: Wha...WHAT!?!? That wasn't me! That was The Underpants Monster!!!!
Kim: Oh, I'm sorry for yelling.
Zach: Damn right you are! (slaps Kim's ass)

Any person that has large weight gains while having the munchies. They usually go straight for the fat foods such as Twinkies and cup cakes, once they find your food your out of luck. They also tend to leave some pleasant surprises in your toilet, so it's best to let them outside once their done eating.

Everyone has a millimeter monster until puberty.
