tool

1. A person, almost always a male, who tries (and believes he is) to be hard or cool by the way he dresses or acts.

2. A very ignorant person who is used to by others without knowing it.

1. Look at that tool in the tapout shirt, with a single ear ring and his hair gelled.

2. I feel bad for that guy, he doesn't know that his dream girl is just using him as a tool.
