The fabled Quad Tit-Fuck occurs when two females press their breasts together and a male has sex with the crevice that forms in the center.
Player: "Dude, I had a threesome with these big boobie bithes last night!"
Punk: "So what, dude, you've had threesomes before."
Player: "I know, but this time I pulled off the legendary Quad Tit-Fuck!!!"
