a way of saying "I'm leaving"... first seen In the movie "Reality Bites" at the very end of the movie in the parody of Lalaina's documentary for In your face tv... the character Roy, based on ethan hawked Troy tells Elaina, based on Winona Ryders Lalaina, "Im outie 5000"... the character of Roy is played by evan dando.
A belly button that is neither an innie nor an outie. Innies are completely inward, and outies go past your abdominals (and are completely sick). An innie-outie is the most common of all belly buttons, and most people with this certain attribute are filled with contempt over their unattractive belly button. Like me. They also cannot get their navels pierced because it just wouldn't look good.
" Man, what the hell? I've got an innie-outie belly button, so I can't get a fucking belly button ring! Shitskies!"
"Yeah, Sha is super jealous of those Dantity cane girls and their hooker belly button rings. Bitch can't get one because of her innie-outie."
intoxicated, drunk, smashed, wasted, sloshed, tired, stoned, high, ripped, wrecked, blotto, fubar, basically not oneself or out of one's mind. also, something you say when you're leaving.
"man, that was a great party. i was so outie boy." "wow, she was totally outie boy from drinking from the sippy cup."
or..
"it's been good talkin to ya...but im outie boy."
