Simply put, a dirtster is a hipster who's just dirty. Hipsters are carefully put together as to look like they just woke up and suddenly looked this cool. Dirtsters are subtly different. They did just wake up and, unlike the hipster, just put on their only pair of pants.

They are known for drinking cheap beer, smoking cigarettes that have already been half smoked, dumpster diving, asking "are you going to eat that?", and smelling just a bit funky. In a dimly lit, well ventilated environment, the hipster and the dirtster are almost impossible to differentiate. Careful attention to behavior, however, will revile their true identity.
If you are a bartender:

The Hipster orders a local micro-brew. A dirtster orders Lionshead, PBR or whatever is the cheapest beer.

If you are dating one:

Hipster has an iPhone, a small garden in the back of their studio, listens to NPR and buys you vinyl and vintage clothing.

Dirtster has an old iPod they 'found', lives with at least 5 other people, and buys you items from salvation army stores.

Like a hipster: skinny, from the suburbs, college radio gone indie record intern, in the know, tragic asymmetrical hair, semi hidden tattoos, knows the bartender, sleeps all day, eats sandwiches, lives in Williamsburg - NYC, loves the "L", rich parents that care.

Has name like: "Elliot"

The Dirtster takes it to another level, anemic, from the country (can shoot a gun), doesn't know shit and brags about not knowing, doesn't work, tragic non-sensical mess of a 'do, tattoos all over, sometime doorman, doesn't sleep at all (drugs), doesn't eat, lives in Bushwick, rides beat to shit dirt (ha) bike from swap meet, really rich parent that hate them.

has name like: "Cain"

Dirtster = trusta-hipster = ex-trustafarian

A Dirtster is a Harley Davidson Sportster motorcycle customized for dual-sport riding (on paved and unpaved roads).

The original inspiration for this style of custom motorcycle was probably Harley Davidson's XR750 dirt track racing motorcycle. Dirt track racing is like oval stock car racing... with motorcycles... on dirt.

That said, the typical dirtster usually looks not at all like an XR750. Dual sport motorcycles that do look like XR750s are known as street trackers.
When I do a web search for dirtster images, I get a lot of pictures of Sportsters with dirt track tires, and not many images of dirty hipsters. What's that all about?
