Warning: Use of laser lights at a Kanye West concert will result in Kanye embarrassing the crap out of you, and shouting, "You gonna get f**ked up!"
One fan at Kanye and Jay-Z's "Watch the Throne" show learned that lesson the hard way during one of the duo's Paris shows. When the guy flashed some sort of pen laser onstage ... Yeezy shut down the show and shouted, "You see this guy right here with the green laser? Don't f**k up everybody's show ... it's not a f**king game!"
The crowd rained down boos (en français, of course) -- then Kanye went in on the dude a little more ... "You gonna get f**ked up, kicked out, and all that s**t. Chill the f**k out."
