When you register an off-road vehicle so it can be ridden on the street, such as a dirt bike, atv, utv, or military vehicle. You can't always just walk into your local DMV to get it registered, so you have to use a special process, often called getting Dirt Legalized.
A dirtleg is the lowest form of a dope whore that one can become. Usually a female that will sell any and every hole or crevice on her body for drugs. Oftentimes, she is dirty, trashy, overweight and lives in a hotel with the dope man. Once he’s had enough of her shit and cuts her off, she moves on to the next dope man.
One that is considered to be of the lowest standards when compared to the bottom 1% of the U.S. This may include overwhelming body odor, underwhelmingvocabulary, and terrifying looks/styles.
