This photo is… gripping to say the least.
We think this pic would be in better taste were the two subjects of this photo a little more non-violent, but we understand this was all done in good fun.
"Had fun with the homey @Chrisbrownofficial"
We're glad that they had fun, you know, recreating a pretty violent way to hurt somebody.
Some people never learn.
