An exclamation at something crazy and/or surprising. Popularized by the critically acclaimed Grand Theft Auto IV video game. Random pedestrians in the game would sometimes yell "Cheesy vagina!" when the player caused mayhem in the city streets.
Niko pulls out an AK-47 and aims it at a pedestrian on the street.

Pedestrian: "Cheesy vagina!!"
