I personally don't think it looks good at all. When you're in high school you can kind of get away with it but after that no way. It looks trashy, crude and silly. There is nothing attractive about a guy's ass hanging out of his pants. It just is so... classless... I like looking good, put together and nice. I don't judge people for what they wear but the style itself I have no qualms commenting on. The style is ridiculous and it makes you look ridiculous. I honestly can say I never did, don't and never will understand why people think it looks good or why they like wearing it... Can it really be comfortable? It doesn't seem like it would.
I can`t explain why it looks good because whenever I see this it reminds me of the movie Clueless. It is not attractive or cool to wear your pants below your ass. To me this just shows that they are immature and still trying to find their way in life.
