Could be a dumb person or whatever like most people on this website say, tool but I'm here to state another definition. A tool could be known as a small weapon. Also known as peace.

A person, typically male, who says or does things that cause you to give them a 'what-are-you-even-doing-here' look. The 'what-are-you-even-doing-here' look is classified by a glare in the tool's direction and is usually accompanied by muttering of how big of a tool they are. The tool is usually someone who is unwelcome but no one has the balls to tell them to get lost. The tool is alwasys making comments that are out-of-place, out-of-line or just plain stupid. The tool is always trying too hard to fit in, and because of this, never will. However, the tool is useful because you can use them for things; money, rides, ect.

A person with an overly inflated ego who happens to think he’s the baddest mother fucker to walk planet earth and never hesitates at any chance he gets to remind you of that. They usually put a TON of effort in trying to come off much cooler than they actually are. Also usually for the most part unemployed.
