I've been conducting a good amount of research lately, jus peeping skater's in their natural habitats, and I've found that one can tell a lot about the skateboarder based on what color dickies they prefer. I will share my findings in hope that we can all understand ourselves and others a little better.
Black: This is the choice color of the modest skater, who none-the-less desires to be somewhat fashionable, but not dylan fashionable, more like heath kirchart fashionable. You can find them in a variety of settings, they tend to lurk a little harder than others, and their cool outer persona masks a deep and emotional inner world. They often prefer the slim ones too.
Blue: The blue dickies are like the most common it seems, they could be the "gateway dickies" that former a jeans wearer chooses. They are also synonymous with the blue collar life style, so skaters who prefer them are also likely to enjoy tranny, cheep beer, working in mail rooms, and squalid living conditions. There are less obvious ties with punk music and Jason Dill.
Brown: Those who choose to rep browns are signifying ties to a prominent gang of skaters/artists. They are like the Crips of cellar doors. Key members are Kevin Coakley, Anthony Poppalardo, and Bobby Puleo. However, I should note that apparently Julien Stranger owns more than 50% of the stock in brown dickies (NASDAQ DBD).
Khaki: The preferred color of Dirts. If a skater owns even one pair, you can assume they have connections, however remote, to Florida.
Green: The least common color, green dickies are sort of ambiguous. Basically they are most similar to brown in what they symbolize, but since they harken to the days of army surplus pants and cargo pants, wearers signal an underlying alliance with '90s skate values.
Gray: Gray is a shade not a color, it is the midway between white and black, it represents harmony. In skateboarding it also represents the unity between scumbag hill bomber hesh-dog and '90s hip-hop ledge/manual technician. Think Rob Welsh.
That weird torquoise/green/blue-gray garbage man color: I haven't seen many skateboarders wear that color, it is like that weird color that crust punks and homeless joes wear. They are the most common color in Salvation Army. If you see a skater wearing those ones it is recommended that you act with caution, as they may turn out to be Duane Peters.
This concludes my research and I hope you come away with at least one bit of knowledge that you can apply to your local homoscape. And if you see someone with a skateboard who is just lurking there, not skating but watching other men while he sits alone like a faggot, dont worry. It's just me and my black dickies.
