Also "hop up." Used when referring to airsoft guns. It is best described as the backwards spin that the gun is designed to put on the bullet, making the bullet spin the wind below it during "flight" so that it doesn't descend as fast. A lot of airsoft guns have too much hopup, so the bullets might travel upwards at times.
Crap, this gun sucks. It has too much hopup.
Sweet, that gun has just the right amount of hopup to shoot straight.

An exclamation made when your friends or family are teasing you to a point where you can't handle it anymore and a hissy fit is in order.

Derived from a YouTube user's famed outburst following Britney's lackluster performance at the 2007 VMA's.
Sarah: 'OMG Susan, I can't believe you are wearing the same skirt as yesterday. Oh, and by the way, EVERYONE knows what you did with Kevin on the weekend. Plus you look a little fat, are you retaining water?'
