A square shaped bush on a woman that is dyed in the pattern of a Rubiq's cube. If you're able to manipulate it so that it turns one color, the woman will no doubt be turned on and ready to have a sexual encounter with you. It was first seen in a portable toilet at a Van Halen concert in Battle Creek, Michigan in 1986. Ken Burns is in the process of finishing a 10 part PBS documentary about the history and cultural significance of the pubic's cube.
stoner: "dude Katie is hot and all, but her bush is dyed all sorts of colors and shit, it's fuckin weird."
friend of stoner: "yeah bro, sounds like she's got the old pubic's cube going on down there."
