Your Top Grammatical Hates...

[dunover]

Having been listening to radio today, as well as reading forums, my blood has started boiling again due to common and stupid errors people keep making when talking or typing. I would like you to help me create a top-10 of grammatical grievances that you hear that really get on your nerves. I have heard and seen a total of four today:

1. 'Pacifically' (specifically)
2. 'Shouldn't of' or 'couldn't of' (shouldn't have)
3. 'your a fool' (you're a fool)
4. 'you know' interjected into every pause when someone is speaking and cannot create proper continuity.
