look up any word, like smh:
 
1.
A term used by "Mike Stud" and "Trey Songz" to replace the word "Yeah" but to also express extreme satisfaction from alchohol women and parties. this term is often shouted by them for the world to hear and sounds funny as hell if used correctly.
Listen to any trey songz or mike stud track in the begginning or end for "uhyuu"

"The turn up was real last night uhyuuuu!"

Friend: "Yo you fucked that girl last night?" Me: "Uhyuuu!"
