PopUps: Justin Bieber's Swag Causes Skateboarding Wipe Out

Sometimes you're dripping with so much swagoo, a concentrated version of swag (according to Kanye at least), that it prevents you from doing things you enjoy, like skateboarding. Just ask Justin Bieber, who wiped out hard while trying to skateboard down two sets of stairs in New York City this week because his pants kept falling down.

"My pants keep falling down!" the now platinum blond pop star yelled in a new viral video that shows the singer failing at pulling off some skateboard moves down the steps of Madison Square Garden, Spin points out.

The Biebs was wearing black leather pants, and a very long grey t-shirt (or a short dress??) while trying to land a skateboarding move while onlookers watched and fans recorded him. After several tries, the "Beauty and the Beat" singer finally pulled it off, but it doesn't matter because the Internet got what it really wanted: Bieber eating it. Hard.

Still, the pop star recovered gracefully, tried again then, before you knew it, he pulled a Bart Simpson and high tailed it out of there on his little board with wheels and vanished into the urban jungle, leaving us to wonder if he'll ever return. Unfortunately, he will be back, but between now and then next time he does something stupid, watch him wipe out in the video clip below!
