The very slight and sexually arousing slit that appears when a woman is barely exposing just enough of her cleavage (also known as breasts, "titties", "honkers", "jugs") so as to entice straight men and lesbians. Can often be far more titilating (pun fully intended) than a woman exposing all her top half immediately.

Someone who used to be a potential girlfriend/boyfriend, but no longer is.

A varied slang term used to substitute the word "Cleavage".
