look up any word, like fluffer:
 
1.
(cantonese chinese)
literally means "die hit street"

"say poke guy" refers to a bullet in the back of the head,
execution style,
and the subsequent faceplant after.

Face "hitting the street".
So pretty much it means "fuck you", "go fuck yourself", that kind of thing.
Say poke gai, I told you to stop looking at pr0n on my work computer!
