Some of mine?
• People who use the word "irregardless". By saying irregardless, you are actually saying the opposite of what you really intended. The word 'regardless' already means despite or without regard, and the prefix –ir is a negative, so irregardless would mean not despite or not without regard, which is illogical.
• People who butcher the phrase "... couldn't care less" by reciting it as "... could care less". If you could care less, you would. This makes no sense.
• People who who butcher the word "supposedly" by reciting it as "supposebly". Please, for the love of the english language, stop making up words because you're too lazy to understand how to pronounce the real one!
• Cotton balls. Seriously. Can't touch them. No idea why. Sends nasty chills down my spine.
I know I can't be the only one here with a dumpster full of them.
What are some of yours?
