General   (General discussion, talk about anything.)

Using the word "like" several times in one sentence.

Saying "basically" and "obviously" too often.

Agreeing with Joe Maplin with "so" to start each sentence.

These are filler words, and totally unnecessary.

Oh, and using the word "of" instead of have. That's probably the worst one.

Then there are sentences which include double negatives, e.g. I've not done nothing wrong.
