The use of the word 'more' when it's completely unnecessary.
'yeah that is more bigger'.
NO ! It is simply bigger.
Americans who refuse to understand that the word 'caramel' is not pronounced or spelt 'carmel'.
I tend to shout at the computer on that one
We all believe we are the world's best drivers and everyone else on the road is a moron who should not have a licence.
My driving peeve is people who have absolutely no clue how wide their car actually is.
If you had a mic in my car I suspect that the phrases: 'Oh come on you could get a bus through there !'
And: 'How bloody wide do you think it is, it's a poxy
(substitute any small car here) bloody ford escort !'
Would be recorded almost every day
