look up any word, like sex:
Cleavecheese occurs when a woman is eating, and food particles accidentally spill into her cleavage.

The particles then ferment in this warm, cavernous environment and if left untreated, transform into a mold-like substance called cleavecheese.
"Dude, did you see Mrs. MacDonald's cleavecheese when she bent down? It was all brown and shit."
