A slang phrase, used by professionals in the motorcycle industry. Often to describe male riders, who are overly fashion concious, ride with reckless disregard to others, are abundantly cheap when purchasing quality, safety equipment, and are generally ignorant of the specifics of their own machines. These people are frowned upon by serious enthusiasts of the sport, as they set a bad example to others. They view motorcyles, not with the respect and responsibility they command, but simply as an extension of their penis. Frequently the cause of accidents, and subsequent high insurance rates.
"Dude's first bike, was a GSXR 1000. And he rode it, in shorts and a t-shirt. That MOFO was PURE street squid.".
