Vair

Vair is short for very. Wait...SHORT for very? What? It only saves one syllable, and has the same number of letters! WHY would anyone use this word? It sounds so stupid. "This iced chai makes me vair happy." See? Ridiculous! The word has like...negative euphony. All people who use this word must be punched somewhere both painful and unusual.

Toosh

I've heard this word a couple of times on TV. Most recently, I saw it on an episode of Skins (a good, trashy British show about high school age kids who are, themselves, pretty damn trashy). Toosh stands for touché, the French word which is mainly used to say "A ha! Good point. You've got me there." Or during fencing, if you are a pretentious a-hole.
