* sagging pants. You literally look like a subhuman.
* Using the Nword (specifically for black people this can be an indicator of low-class and also a major sign of little to no pride in being black)
* Profanity is probably the biggest indicator tho, especially if the person uses it around anyone with no regard / respect for strangers, elders, children, etc.
* A person's choice of music can be an indicator also. All I'm gonna say on this one is if I'm given the choice to be in an environment with brothas who mainly listen to jazz and R&B or brothas who mainly listen to drill and trap.......I'm going with the brothas who listen to jazz 100% of the time.
