1. A person who not only speaks too much, but also talks about things that don't matter at all. Even if the things they talk about were important to anyone, they would be wrong.

2. Someone who argues on subjects that they have no claim of expertise on. In fact, they know nothing about it; or anything else for that matter.

3. Tom Cruise

Bill: Man, my internet sucks. I think I'm gonna switch ISPs. Anybody have any suggestions?

Tom: AOL is fantastic! Even if I didn't get internet service from them I would pay the 20 bucks a month just for the instant messenger and chat rooms and stuff!

Ted: *sigh* Tom, you are such a butt tumbler...
