first see if u are over weight, if u aren't don't worry about it. besides, jeniffer lopez had surgery to get her butt big. and if u REALLY think u have a big butt, i mean u really have to think about it if u do or not cuz alot of people just say that to be either mean or just havin fun with ya, but if u really think u have a big butt then walk more or somthing, or get a video called "buns of steal" lol.
