The Negro tends to be annoying, what has been your worst encounter with them?
Personally, I am most annoyed by negroes in the lunch line given that they always act like total buffoons, cut each other in line, then threaten to fight and mug you if you don't let them.
However, I might be a bit selfish here. I personally know of some people who have been literally shot on the streets by negroes at night.
