A word used to define one's best mate. Your pally-wally. Your mate-a-roo. Your fo-real-shizzle. Your best friend. Except in this case, you get to pretend you're five and have little to no knowledge of pronounciation. Kind of like Paris Hilton. It's also preferable to use this term with a high pitched baby voice. You know, so you can get more attention and look like an airheaded douche bag intead of a well educated human being.
And then I was like, why are you so obsessed with me? We haven't been like bes franns since my boob job.
