This question already has an answer here:
I always liked to use the word "crackers" to refer to people who overcome computer software or security restrictions, as opposed to "hackers," which (supposedly) originally meant people skilled at computing.
A while ago, I used the word in my conversation with a speaker of AmE, who did not know of that use of the word and thought I was using a racial slur. This could have been a problem since I am not Caucasian myself.
While I could use other words like "script kiddies" to roughly mean what I meant by "crackers," this left me with the following question: is the use of the word "cracker" as a racial slur so common that it cannot be used to refer to certain hackers without causing misunderstanding? My assumption is that it may depend on where you are: if you are in the Deep South, probably the word is more commonly used pejoratively than elsewhere. But I don't know that for sure.
