I dislike "like" when used as filler. As in "like, you know, like I said like, hello??". Grr...
Plus I hate sentences that are supposed to end in a period that end up sounding like a question. To wit: "I'm going to the store? To get some shoes? I'll take the car? It'll be great?"
I hate that!
When people start a sentence with...."I'm not being racist but....."
They always are.
Yeah, I second vote that one, to be one of the most annoying, along with I am not sexist, but....
if people say "oh" after u said something rather interesting. just "oh" and that was it. I really hate that. "oh"
When someone says: "How can I help you understand..."
You can't. Go away.
