steakface

Annoying/Pretentious vegetarians who deserve a slap in the face with a steak.

Arse

Another word that pompous Brits like to hold over American's heads as they talk down to them about the meaning and spelling of the word.

It means butt. It's that simple, yet that big of a deal, apparently. Anything to help keep their smug egos aloft... otherwise they'd be crushed under the sheer weight of them.

Brit #1: You're saying it wrong!
Yank #1: Well, since this is another country, words tend to be spelled and pronounced differently. It's called an accent. Don't be an arse.

ninja-esque

Having ninja-like appearance or abilities.

Leonardo: Are those guys... ninjas?
Michelangelo: "Well... they're certainly ninja-esque"
