look up any word, like ratchet:
A girl that has an extremely cute butt, not too big and not too small and resembles a Kimiziki. They are normally super sexy and have great singing voices. Almost any guy wants to have a Kimmybutt because they are irresistible and the sweetest people you will ever meet.

They are normally of the Filipina persuasion but can be found in America. They are extremely exotic and rare to find and anyone who see's one wants to have one.
Guy1: "Bro! did u see that girl and her butt? She was
irresistible and seemed so nice."
Guy2: "Common dude, you know that's my Kimmybutt..."
Guy1: "Oh yea! sorry!!"
