Saying that someone or yourself is dusty or getting dusty is referring to how messed up you get and therefore how awesome you are.

Dusty is in reference to hittin "Duster", otherwise known as whippets. Specifically in reference to inhaling high pressure air from the cans that are supposed to be used for spraying dust off computers and such.

A guy who's been through a lot but manage to keep a smile all day everyday-- THUG. <3

A man or a woman with an amazing sense of themselves. Someone who gives with thier while heart. Can also be someone who if broken can be someone cold as ice. Dusty is usually someone who will give the shirt off of thier back to anyone in need, but will not feel comfortable asking for help.
