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.

1. Shortening of the word "University" (=College)

"I'm got classes at uni this afternoon"

2. A prefix derived from latin meaning "one" or "single"
"A unicycle only has one wheel"

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!"
Girl 2: "WTF I would totes hit up the salon so hard if I had a unis!"

(replacement of unicycle)
Girl: "That man is riding a unis throughout campus! What a toolbag!"
