3.
A replacement for words containing the prefix, "uni-". Has a more negative connotation than mainstream words such as, unitard, unicycle, uniform, unibrow, and the like. To clarify, in speaking to a friend, the term unibrow is more appropriate; for an enemy, unis is fitting.
(replacement of unibrow)
Girl 1: "OMG look at her new default! She's sporting full facial hair-- a stache, beard, AND unis!"

(replacement of unicycle)

When a person quickly and sharply slaps another person in the forehead, creating one of those classic "what the hell?" moments, which always tend to be fun.
RULES:
1. You MUST say unis when performing a unis on somebody. It is pronounced (yoo-nIS).
2. It is MANDATORY that it be on the forehead. If it is anywhere else on the body, it is null and void.
3. It is IMPERITIVE that it be a slap. Don't punch people in the forehead. You'll look like a complete retard, and it won't count anyways, so it'll just be a big lump of fail.
Dustin: (slaps John on the forehead) UNIS!
Jonathan: Damnit Dustin! What'd I tell you about that?
Kreig: (also slaps John on the forehead) Unis!
Jonathan: SON OF A BITCH!!

uni
Short for unisuit, a one piece spandex thing worn mostly by rowers. It is basically what you would get if you took a pair of spandex shorts and joined it to a (spandex) tank-top at the waist. Rowers/coxswains racing uniforms are almost exclusively unis, however they are also worn for training. Often racing unis are printed in a similar pattern to the team in question's oars, or at least in the same colors. Usually the shorts part is longer than normal spandex, like mid thigh, so they give you seriously annoying tan lines because they are hard to hide. Dress shopping is seriously annoying with a uni-tan. They also make it hard to pee.
We aren't allowed to wear our racing unis until race day.

Getting new unis is the best!

Damn uni-tan, guess I won't be doing booty shorts this summer.
