A sexual position requiring two women and one man. One woman sits on the other's face, allowing the woman being sat on to provide cunnilingus. The woman receiving cunnilingus must position her posterior parallel to the other woman's breasts. At that point, the man may enter and slide his penis between one woman's breasts until he enters the other woman's anus. This creates a "cheeseburger": two buns, some cheese, and meat.
James: Dude, seriously, why can't I ever get a girlfriend?
Matt: Because you always fucking ask them to get together with Cher and give you a cheeseburger!
