Bracket Eight is the correct way to explain the sexual act called "69ing" or "sixty nining." The man's penis goes into the woman's mouth and the man's tongue goes into the woman's vagina, therefore the man is the bracket. The woman is represented by the "8" because both extensions of the bracket penetrate the openings of the eight "8," the mouth and vagina of the woman.

{8 (The real bracket cannot be used on Urban Dictionary)

A man who messes around with other men, but no one would ever know by looking or talking to him. Used by gay black men to identify masculine gay men or DL Brothas.
