Seth Rogen, like many human beings with the ability to see and hear, is not a big fan of Justin Bieber. Yesterday on the Howard Stern Show, he explained why.

"He's a good example of someone you meet, who you think you're going to hate, and then you get to hate him as much as you thought," he said on the show. "You meet him, and he lives up to every one of your expectations of how you hope he will be."

Rogen said the realization came years ago when they both appeared on a German talk show. At some point someone came to Rogen's dressing room and said Justin wanted to meet him.

"And it was weird, I was like, 'Sure, I'll meet him.' So I went outside to meet him and he was acting like I asked to meet him. It was very nonchalant, 'Yo man. Wassup,' and I was like, 'What the fuck, I don't give a fuck about, I don't want to meet you. Don't act all nonplussed to meet me. I didn't want to meet you. I was totally cool not meeting you… But I was like, fine, I wouldn't have said anything, I was like, 'He's a bit of a motherfucker. Whatever. He's young, the kid's a dick.'

And then I met him like two years later maybe, I saw him again at an MTV awards show and he literally had a snake wrapped around his fucking wrist that he was wearing as an accouterment and I was like, 'What the fuck,' and I talked to him for like five minutes and I was like, 'Fuck this kid.' He was trying to be funny with like, 'Hey this snake.'

Rogen also clarifies that tween heartthrob and late-night troublemaker Justin Bieber is nowhere near as cool as tween heartthrob and late-night troublemaker Zac Efron (who he is currently co-starring in a movie with.).
