The lyrics in question come in around the 4:50 mark:
"I see the btch in you Caitlyn, I keep the pistol tucked like Bruce Jenner's dck. No disrespect though, not at all. No pun intended, that took a lot of balls."

"It's all in fun, man… I just say sh*t to say it. It's very rarely personal."
See, he was just joking. What do you think about that, Caitlyn?
