There are a few things we know about Post Malone. The “I Had Some Help” singer is unfailingly polite, can 100% rip a Nirvana cover anytime you need him to and is a self-proclaimed master beer pong player.

Except, that is, when he isn’t.

According to Taste of Country, in a recent chat on CMT, Kane Brown revealed the story behind the picture that circulated a few months ago of himself, Posty, Jason Aldean and Jelly Roll playing beer pong at last year’s ACM Awards. Brown said he was teamed up with Jelly and, not for nothing, they beat Post and Aldean.

Because the internet is filled with haters, Brown took the opportunity to clear a few things up about the victory. “A lot of people are like, ‘Oh, who do you think won?’ A lot of people are like, ‘Oh, it’s Post and Jelly, ’cause they play all the time,’” Brown said. “Wrong! Man, I was killin’ ’em!” he added unequivocally before sharing the price Malone paid for the loss.

“It was water in the cups, it wasn’t beer,” Brown said. “But, he [Post Malone] was dumping his cigarettes in the last cup, and the table was super long. I was like, ‘I’m gonna hit this cup.’ He said, ‘If you hit this cup, I’ll drink it.’” Brown said he then made eye contact with Aldean and knew exactly what needed to happen.

“I looked at Post, and I said, ‘Drink up,’” Brown said he told Malone after landing the ball in the cup. “Jason just went, ‘Oh my God.’”
