Tool: (noun)

1.) A guy with a hugely over-inflated ego, who in an attempt to get un-due attention for himself, will act like a jackass, because, in his deluded state, he will think it's going to make him look cool, or make others want to be like him. The person may even insincerely apologize later on, but only in an attempt to get more attention, or to excuse his blatantly intentional, and unrepentantly tool-ish behavior.

2.) Someone whose ego FAR exceeds his talent, intelligence, and likeability. But, of course, he is clueless regarding that fact. He erroneously thinks he is THE MAN!

3.) Someone who others normally refer to as a prick, dick, or schmuck.

4.) Someone who acts like a dick, because...well...he's compensating.

5.) Kanye West
Example:

Observer #1: Hey, did you see Kanye West's idiotic stunt at the awards show?

Observer #2: Oh, you mean, "Mr. It's-All-About Me?"

Observer #1: Yeah...what an asshole.

Observer #2: I know. He's such a tool!

The first against the wall when the revolution comes. An inferior, low or no-self esteem individual who gets off obeying authority figures. One used by his superiors, who themselves undoubtedly would kick them to the curb in a heartbeat. Nevertheless, the tool believes they are worthy and significant STRICTLY because they have attached their whole sense of self to obeying said authority and/or submitting their individuality to another. Could be a woman...but is much more pronounced when seen in a "man".
Glenn Beck is such a tool for corporate power, bending over and spreading cheeks for hateful robber barons who are raping the working poor with their usurious practices.

Get a Tool mug for your brother-in-law Bob.
A douche-bag teenage boy who wears only name brand clothing, follows every trend, uses 'fag' as his primary insult, thinks he is cooler than everybody else, relies on "that's what she said" jokes, talks loudly about how many girls he's gotten it on with, has a poor sense of humor, and is just an all-around ass-hole. Usually reasonably wealthy/spoiled. Often accompanied by several sluts.
God, he is such a tool, I hope I'm never like him.

An individual who behaves in their own self interest rather than adhering to a set of beliefs or morals. Someone who will act as though to seek approval on the outside, but is actually quite vain and selfish. Men of this variety tend to cheat on their girlfriends. Women tend to use men to obtain free drinks.
God, Brett is such a tool.

My, and a whole wack of others favorite band.
An awesome band who redefined many genres, and made many bands look like crap. Lead singer also in A Perfect Circle, another awesome band.

Its true about not being able to compare tool and apc AT ALL, but i do find this quote quite humorous:
"hey, listen to this A Perfect Circle record, its like tool without the anal sex"
~Who ever wrote that is awesome, although I completely disagree, but its still funny.
This unbelievable band consists of:
Adam Jones on guitar,
Danny Carey on drums,
Justin Chancellor on bass,
Maynard Keenan for vocals

Albums:
1992-Opiate
1993-Undertow
1996-Aenima
2000-Salival
2001-Lateralus
"Oh my god!! Tool is definitly the (or one of) best band(s) of all time!!!"
"Most Emo should die. Along with every 'nu metal' band that is destroying the music industry. Oh, pop can be removed too."
"Half the population of tool lovers also love Nine Inch Nails, and A Perfect Circle, but they're not for everyone"

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.
"Let's drive to Chicago from Iowa. Oh man, we need money. Hey, let's ask tool to come, he'll spot us the cash!"

"Tool is our friend. We call him that because he is one."
