When YG raps "FDT" he means it. And if you don't rap the anti-Donald Trump anthem along with him, he has a problem with you.

One of his fans learned that the hard way during the Bompton rapper's recent show in Tempe, Arizona.

“You didn’t sing not one f****** lyric, I was watching you. You didn't say that s*** at all. Then I asked you, 'what's your nationality,' you says you white. So I'm like, 'oh OK, it makes sense," YG said to the offending fan.

"I wanna ask you a question. 'Is you with Donald Trump or not?' I couldn't tell when I was performing."

Do you want politics at your rap show?
