Do you believe in UFOs?
The answer of course being, yes, I do believe there are aerial objects which have not been identified.
So, what other things that people say do you find irritating in this way?
Another one of mine being: in the UK we have a 'washing-up' liquid called Fairy Liquid, which a lot of people call Fairy-Up Liquid. I can't explain how annoying this is.
Idiot disclaimer: this thread isn't about UFOs.
