Battle rap can get pretty intense.
It is two (usually) men yelling insults at each other within close range, after all.
A recent battle rap event in Philly went left when one of the rappers, Stampede, was stabbed.
Stampede's girl Ms. Miami went on Live after the stabbing to rage about what happened. We also have a video with a more clear-headed discussion of what went down.
The good news is Stampede is going to be OK.
Be careful out there.
