3.
A person (contrary to popular belief, can be a member of either sex) who regularly frequents the discothèque. Can often be seen posing, wearing the latest trends in clothing including shirts with lame, bold slogans & wearing sunglasses inside & at night, handing out club discount entry passes so they can brag about being a promoter, attempting to sneak into the VIP area & gurning their face off from munching too many disco biscuits.
