Is it normal that i want chris brown to sit on my face?

I think you'd have better luck getting him to punch your face.

Totally normal, I've heard he's quite handy as well.

I want Chris Brown to eat dog shit!

"Sit on my face,"

I think you've got your expression confused there.

Here are two definitions from Urban dictionary for "sit on my face":

"An assertive lover or drunken one night stand might use this phrase to be direct and to the point of wanting to eat the lucky womans[sic] pussy."

and

"A compliment to women, implying they are usually good looking and attractive, but not nessacerily[sic] meaning the person whats the female to sit on his face. "

Used in this context, it sounds like you want to give Chris Brown a rimjob.

I thought that guy was hella hot like celeb crush when I was younger lol I heard he got a daughter now, im more into his music now. Dreams are for free haha

I hope he doesn't see this post of yours. He gets way too many female stalkers.
