An exclamation of intense excitement or extreme satisfaction, primarily upon accomplishing an achievement, winning a competition, or when expressing pride in an organization. Also can be used as a battle cry.

Originated from Kirbypenguin's frequent use of the word, perhaps inspired by woot or woo hoo.
Kirbypenguin: I just got 99 Fishing! Woo Loo Loo!
