OMU 

Occasional-Marijuana-User:
This guy is friends with many pot heads and loves being around them when they are high but he only smokes with them ever once in a while. He is often sitting back and observing their idiotic decisions, He hates being called a pothead and denies that he smokes at all costs.

Pothead 1: bro this is somr good ass weed, take a hit!

Pothead 2: Hell yeah ill have a hit. What about you Dave?

Dave: I'll pass. Im good for now.

Pothead 1: Nah hes a fuckin omu, hes probably talking shit about us righy now.

OMU 

meaning 'oh my Urie', referring to Brendon Urie of Panic(!) at the disco. Commonly used by my friends, because they get annoyed that i say oh my Stump a lot. used as a replacement of god/gosh in the phrase 'oh my god' Originated in Pennsylvania, to my beliefs. can be alternated to omfu, meaning oh my fucking/freaking Urie.

One of My Friends:"OMU, Brendon Urie's voice sets my pants on fire! Epically when he hits the high notes! *giggle* <3"
Me: "I know!!!! Wait, did you just say OMU?"

Omunique

She bomb ass fuck. She don't like to be loud and self- centered, but people make her act an ass. Omunique doesn't really care about people, but deep down in the cracks and the crevices she doesn't give a fuck. She thinks she ugly but she pretty as hell. Omunique feels like females shouldn't talk shit if they can't throw hands. Furthermore, she is a light hearted girl who just wants loyalty, respect, and honesty.

If Omunique Had A Pockets Full Of Fucks She Wouldn't Give A Bitch One.
