Emimem vs Chris Kirkpatrick
Eminem's tete-a-tete with former *NSYNCer Chris Kirkpatrick started when the rapper sang of his distaste toward boy bands. Kirkpatrick did his best to stand up for the genre, but Eminem got in the knockout punch in his 2002 song "Without Me": "A-tisket a-tasket, I go tit for tat with anybody who's talkin this s***, that s*** Chris Kirkpatrick, you can get your a** kicked worse than them little Limp Bizkit bastards." Nothing gives you street cred like picking a fight with a boybander.
