1. Noun: A Yo-bro is a west coast white boy who is prone to wearing flip-flops and beat-up cargo shorts or board shorts. He carefully dishevels his hair, hangs out the window or balcony of his apartment with cheap beer in his hand, and tends to yell out "yo, bro!" to a fellow bro. These guys tend to be college age, but not necessarily college bound or they are in college but not necessarily in class. But beware, many tend to turn around and join corporate America and then rape you in the ass when they commit white collar crime. Many can be observed in the vacinities of Isla Vista, San Diego, Santa Clara, or Chico State.
Non bro 1 (usually a minority): "Hey man, you livin at the HU house next year?
Non bro 2: Naw, fuck that. I'm moving in with some Yo-bro's. They always got beer and drunk white sluts over.
