look up any word, like plopping:
The act of fingering a woman's vagina with fingers covered with cheesy residue, after consuming large amounts of cheez-its. This act leaves the woman's vag smelling like cheddar jack (or the flavor of your choice), but it can be a tasty plus for afterward oral sex.
Guy 1: Dude, I totally Cheez-it fucked that chick last night.

Guy 2: what flavor did she taste like after?

Guy 1: White cheddar.

Guy 2: Bitchin.
