What did this girl expect? He doesn't know you. He's not going to include you in the picture where he looks super ripped. I'd do the same thing or else you just get a bunch of people asking you who that person is. You're like, "I really have no idea. Please stop asking." Plus, he's the Notorious Conor McGregor. His whole thing is that he acts like a jackass. You're lucky he didn't post the picture and make fun of you.
Last thing I heard about Conor McGregor is that he threw a chair at a bus and hurt a couple of MMA fighters. If the dude wants to get into the WWE, just go ask Vince McMahon. No need to put people in danger. Then again, I'm surprised more MMA fighters aren't seen throwing chairs around.
