Hehe funny story there, when I was in 8th grade, I joked about me having a perky butt, and well it kind of stuck. Soon after whenever my friends and I would walk back to class after lunch, we would always joke about who had the best butts,(weird. I know, but inside we are all a little weird.) and every time it was my turn to boost, I would stop what I was doing turn around, stick my butt out and scream "perky butt 4 Evs!"
