Chug, chug, chug!

Justin Bieber may be known for some of his bad boy antics in the past, but apparently he never learned to chug a beer!

The Where Are Ü Now singer was in Las Vegas to watch his buddy Floyd Mayweather Jr.'s fight and decided to shotgun a beer with his friend Sam Shahidi at a pool party.

Fortunately for us, the 21-year-old singer posted the video to Instagram, unfortunately for JB, he needs a little practice on his chugging skillz!

But the What Do You Mean singer did his best to come up with an excuse by captioning the video:

"I lost but I didn't go to college"

Ch-ch-check out the video for yourself (below) and let us know if you think Justin should be quicker, regardless of not going to college!
