Female member of a gym that makes her appearance more of a priority than her workout. Often found wearing lululemon clothing and making duck faces in the mirror while taking selfies, or whining to other Lulu's about what another Lulu wrote on her instagram.
Look at that Lulu taking another selfie. OR I wish that Lulu would stop whining about her Instagram.
