In the years before Twitter, beef sometimes had real-life consequences. Rapper Jackie-Oand Foxy Brown threw actual, physical jabs at each other, brawling at a Miami studio in 2005. Jackie claims that Foxy’s bad attitude sparked the brawl; Foxy says the fight never even happened at all. Jackie later dissed Brown with the track "TKO."
