It's ok to say Hipster when you're talking about Hipsters.White suburban motherfuckers live in a cultural void. They wind up vampires on whoever they see who has an ounce of soul, whether it's urban blacks, or punks, or hoboes. They make a copy of a copy of a copy of some image they see distantly because they don't know how to create. You'll note that all the neighborhoods crusty anarchist punks squatted in 20 years ago are now "artist" hotspots. Same with clothes and PBR and maybe even traveling itself.
It might just be a skater thing. Recently i have seen a shit ton of skaters wearing bibs. I think its just mainstream "skate culture" biting the style of all the hesh dudes. Anyways im not suprised, i know carhartt has done a whole skating line a coupple years back.... It just weird that the whole thing is catching on now.
