Whoo Ah! 

The lovely sound that comes out of Kim Petras mouth in her songs.

Oh, you can’t do better
You can’t do better (Whoo Ah!)
You can’t do better

Whoo Ah! by liberbermudez October 11, 2018

whoo-ah 

When a person agrees with another or likes something.
Many war vetrans say this

"Knocked out this guy in the third round"

-"Whoo-ah!"

"We'll kick there sorry ass!"
-"Whoo-ah"
