Cracker is retarded. I never even heard that until I was probably in my 20s. Maybe it used to be a regional thing?
I remember me and my cousin when we were kids trying to think of insults for white people, we thought honkey was dumb but its better than cracker. Simply saying "white boy" with a certain inflection in tone was the main insult at my school. I kind of like whitey and pasty face. Pasty face is funny.
It used to be used only for southerners, but it seems to apply to all honkeys these days.
I like "whitey". The guy that played him on Leave it to Beaver was arrested for drugs or something.
