Posish

Posish is short for position (as in sexual position), and my first time hearing it was when I listened to Tenacious D's self-titled album, and heard the glorious song "Fuck Her Gently":

Whats your favorite posish? That's cool with me Its not my favorite But I'll do it for you

Oh, Jack Black. Your douchey words are just plain endearing.

Terriff

Terriff is short for terrific. It's one of those words that I kind of like  in a guilty pleasure sort of way, like fab. The best part is the way I hear the word being pronounced in my mind: "How was your vacation, dear?" "Terriff, just terriff! We spent gobs of money and really painted the town red." Imagine someone saying this the way Gloria Upson from Auntie Mame said "top drawer, really drop drawer": in a snotty,1950s Boston Brahmin-style accent. It's hilarious, and therefore awesome in the world according to me.
