Lil Uzi Vert's goofy festival behavior has been well documented.
At two recent events he's gotten into playful battles with groups of backpack wearing festival goers, resulting in roughhousing and fence jumping.
But in the video below things get a little more serious. Lil Uzi repeatedly tries to attack Atlanta based rapper Reese La Flare, who had made a diss track about him.
You a bitch ass nigga, you a faggot," Uzi Vert repeats, as the security guard keeps him away from La Flare.He's certainly not letting the "lil" get in the way of some serious barking.
