A baseball mascot in Pennsylvania had its named changed from Pork Chop recently because it offended some people. I had not heard "pork chop" used as a racial slur before. Have you?
No way, never heard of this being a racial slur. If anything maybe a chubby little kid might be called this in good humor. I heard they were changing a lot of mascots, but I would not have seen that one being on the list.
