In his 7220 track "Shootout @ My Crib", Lil Durk cops to having a problem with flatulence. 

“I ain’t gonna cap, you gonna smell Percs and lean when I fart," Durk raps.

NLE Choppa and others have offered to help Durk with his farts.

But there's no need.  In a new interview, Durk explained the smelly bar.

"It was really just like being sarcastic.  Sip so much lean and take so many percs your body flooded with drugs and it's like if you fart you can smell it take sh*t. If you really do that, you have to go to the hospital."

Durk's fiancée India Royal probably appreciates that it was all a big, sarcastic joke.
