“Um Yea” is a phrase and adlib coined by Lil Uzi Vert. Migos collaborated on their #1 hit “Bad and Boujee” with Lil Uzi.

“Um Yea” is typically used to emphasize something usually used sarcastically.“ Um Yea” translates to “of course” or “obviously”.

Uzi uses the “Um Yea” adlib, like on “Left, Right”:

“Um yeah, I was just in Miami
Yeah, guess who I fucked on the beach
Yeah, Chanel that’s all in my feet, yeah…
Um, that’s double C, yeah
Walking with that pocket rocket
”

“Put 200k in my safe, yeah (um yeah yeah)
Put 300k in my safe, yeah (um yeah)”
