I dunno if it's just because I dislike it so much, but 'stink' or 'stinky' or 'stinking' seems to be written regularly on different posts. I hate it and no idea why really it's just a word 
It's not even like it evokes an unpleasant memory, like of an awful odour or something. I have no logical reason for my not liking the word. Maybe just the way the k looks kind of sharp at the end, and abruptly finishes the word? And of course it does mean and unpleasant thing, whereas the word 'slink' does not necessarily...See, I told you it made no sense.
Also, belly. Again I can't really say why I don't like this word. I don't have such a violent dislike as in I don't mind other people using it, but would never use it myself.
What words do you hate for totally illogical reasons?
