Inner leg Clevage (ILC) is the space located between a woman's thighs near her vagina. Usually, a "in shape" woman will have space, and her legs wont rub together when she walks, at least near her crotch. A fat woman with no inner leg clevage will have her thunder thighs rubbing together and in some extreme cases must wear flame retardant pants in order to keep from spontaneous combustion.
damn, jessica alba's got some nice inner leg clevage.
When a male wears shorts and sits down to reveal his shorts get bunched upbetween his thighs, leaving what is now known as "crotch clevage."

The curse of the clevage has haunted mankind since the dawn of low cut tops. When your looking through a crowd and suddenly 'WHACK' there's clevage! And even if you don't mean to you cant help but stare just for a second which is just long enough for the holder of the clevage to clock you and then your buggered. For help look up bonzo.
(Looking for someone in a crowd, panning across 'Woopah' theres clevage, pause for a second, realise look awayquickly, be ashamed of yourself. (its not your fault)
