Here are some I've made up:
Defogification: Removing the fog or mist from a glass surface, most often car windows or eye glasses.
Fogification: When a glass surface, most often car windows or eye glasses, becomes foggy or covered in mist.
Snammunwidget: Some unidentifiable or unknown object. Most often something that has no recognizable function of purpose. "No house should be without at least one good snammunwidget."
Some good ones I did not make up:
Heinosity: Being very heinous. Made famous by Edge and Christian in their goofy E&C days. "You so totally reek of heinosity!" Also known as the opposite of awesomeness.
Reekazoid: Somebody who "totally reeks of heinosity." Somebody who "sucks." Also made famous by Edge and Christian.
Chicktionairy: I know I heard this on some TV show, I just don't recall which. It is a guy's address book of girls. By the way, quick note to the ladies of TT, I don't agree with using that term, I'm just coming up with sniglets or neologisms.
Hateorade: A hate-filled beverage that causes you to act like a "hater." I'm sure that this originated somewhere else, but I first heard it used (quite often) by WWE Smack Down general manager Theodore Long. Yeah, I watch too much wrestling. By the way, when I say this, it sounds hilarious, because I can say it in the lamest white guy way possible.
