Second of all, i'm not the one sitting here declaring themselves to be the all knowing martyr of etymology. Or should i say, entomology. You are literally declaring yourself to be the arbiter of what slurs are and aren't i'm merely following what people around me say i can and cannot do.
Also, dictionaries can just be wrong. Dord was an entry in the dictionary for quite a few years. It was supposed to be D or d. not Dord, but it was Dord. Because of a typo. I'm not saying the definition of pansy is wrong, but i'm also not saying it's accurate to modern usage of slang.
Pull up cap in the dictionary, see what it tells you. Google it and see what the slang means.
