Lol, this one is kinda looking weird, even though it sounds hilarious though. Women's butts are curvey not like men that has strong butts. Only very few can claim to have better looking butts and xD.

Even the butts of those chicks are perfectly shaped in most of the series, not of the boys. So that's total injustice with the boys. :laugh: lol
