Also known as "Mom butt," the phenomenon that occurs when the bottom of the ass is flat and the top is wider, like a heart. This is most often attributed to lack of definition caused by a hard life, meth use or over use of stimulants such as caffeine, nicotine and diet pills. Lee or Chic Jeans can intensify this effect. Can be seen at Southern rock concerts.
