Unit 

Unit used in the term of calling someone something can be used as an insult or just for the hell of it. I depends who your calling Unit, and what they have done to deserve the title. Friends calling friends Unit is not considered an insult, but if you say it in a mean way then it is considered an insult.

A girl and her friends are hanging out somewhere and the girl does something silly, her friend say "Your such a Unit!". This is used in a friendly way.

Seeing someone down the street that you dislike and saying "UNIT!" is said in a insulting way, and is therefore not a compliment.
