If you could permanently ban a word from general usage, which one would it be? Why?

If I could ban any word from general usage, it would be any word with more than one /k/ sound as I find that sound particularly unpleasant. Words like cupcake, kooky, cookie, car key, cuckold, and kick. As well as khaki, caulk, and Kierkegaard.

I would however like to hear more words with -rgle, like gargle, burgle, and hamburglar. I also like words with /s/, /w/, and digraph /sh/, like in the word swashbuckler, which is nearly perfect, even though it does have /k/ in it, it only appears once and perfectly accents the other swishy sounds.
