Hmm the word pussy makes me cringe, not sure why... The C word has to be the one i hate the most. Let me tell you a little story about it
As a foreigner, when i first moved to the UK 12 years ago, didn't speak English very well. I used to watch everything with subtitles. Once the C word came up, but i missed the whole context of the sentence, so had no idea it was offensive. The following weekend, there i go meet the family of my other half... Typical Sunday lunch, with the aunts and uncles, and his Nan... I have had a couple of glasses of wine, and was a bit merry, and i was being asked about my culture etc etc... And then, i decided it would be a good time to ask out loud " So.. what exactly is a C***?"
Needless to say, i was traumatized hahaha thankfully his family just laughed at it...
