It is a ficticious institution that honors and celebrates hot babes with smokin' midriff's, stomach's, belly's, navel's, etc...
" you must be a graduate of The Navel Academy, because i have never seen a more sexier stomach in my life baby"
"spring break was frickin awesome. just about every girl there was from The Navel Academy"
tattoos on a girl that are strategically placed around her vagina.
she just got a tramp stamp, the pink ink is around the corner!
it is code for when you and a selected buddy, friend, frat brother, etc...want to have to have a threesome with an escort, slut, whore, etc...
also can be used to describe an threesome encounter that has already occured.
"checkout that little brunette with the tramp stamp and navel ring. let's see if we can pull off a You, Me, and Dupre!"
"last night was great. Eddie and I had a You, Me, and Dupre with Kathy! What a slut!"
