Well, that’s awkward! Nick Jonas stopped by The Tonight Show on Monday, June 13, and he shared a funny anecdote about the time he got an unexpected boner at an awards show in 2014.

The “Champagne Problems” singer, 23, kicked off the embarrassing story by telling host Jimmy Fallon about his experience trying a marijuana lollipop.

“I went to bed feeling fine. Woke up the next day and everything’s in slow motion,” he said, miming the hilarious moment as the audience laughed. “I’m like, ‘Oh no, this is happening. This is real,’ because I had to be up for the Young Hollywood Awards, presenting at the Young Hollywood Awards!”

After a brief moment of panic, he went back to bed. When he awoke a few hours later, things were no better — the singer was hearing voices in the shower and called to his then-girlfriend to get him bread and coffee. Jonas then put on his red suit and hopped into the car to head to the awards ceremony.

“I’m feeling better and then out of no where, I get a NARB,” he recounted.

Fallon, 41, asked the Kingdom actor to explain the cryptic acronym, to which the hunky heartthrob responded, “Look, all men get a NARB from time to time. A NARB is a non–apparent reason boner.”

The TV host then busted out a painfully awkward picture from the 2014 Young Hollywood Awards red carpet, which shows Jonas standing upright with his hands crossed in front of him, covering his crotch.
