The English word of Greek origin "callipygian" indicates someone who has beautiful buttocks. However, the qualities that make buttocks beautiful or well-formed are not fixed, as sexual aesthetics of the buttocks vary considerably from culture to culture, from one period of fashion to another and even from person to person.
Pygophilia is the sexualization of the buttocks. According to Wikipedia, which apparently knows everything, “[w]hile female buttocks are often eroticized in heterosexual erotica, men’s buttocks are eroticized in gay male circles. Much of gay male sexuality centers on anal intercourse and penetration, so the buttocks are eroticized due to their proximity to the anus and the genitals.”
That’s not exactly right, somehow, but close enough. Generally speaking, when it comes to pygophilia, the bigger the bootie the better… within reason. Enter the bubble butt.
Bubble butts have long been a desirable trait. In fact, when tightly packed into jeans, they often translate into free drinks at the bar, lots of bad pickup lines, and some serious grab-ass as the night wears on. An ample arse on Manhunt often elicits messages of “nice butt, man,” or “hot ass, dude,” and other more explicit enthusiasms.
We have this one coach at school who has the most amazing butt. It's truly mesmerizing and since he often wears athletic shorts, I have a greater appreciation for the way shorts can accentuate a man's behind. I often have to tear my eyes away from his cute behind, mainly because I don't want to get caught staring. Sometimes you just have to take in the beauty from behind.
