Wabaloo
You call someone a wabaloo when they are doing something silly, or you are joking with them.
Look at him, that wabaloo is wabalooing around the basement eating Cheerios as he walks in circles.
wabaloo
You say this when someone comes up from behind you , usually a friend, and touches your ass
Joey came up from behind me and tried to grab my ass, so I screamed wabaloo and ran away.
