Someone who is easily manipulated by others, because they substitute the judgment and/or approval of others for their own. The others can be admired friends, strangers or potential mates whose approval the tool seeks. Especially in interpersonal situations, the tool will seek approval from the other, but fail to exercise their own judgment about whether the other person is good or right for them. Alternately, the tool will allow public figures, advertising, or other mass media to replace or form their own opinions on any number of subjects -- most evident in fashion and music choices (often fads or heavily marketed products of suspect quality or style). Somewhat less obvious are tools whose opinions on current events are parroted from sources thought by the tool to be reliably correct -- if you don't follow current events, or didn't come across the original source, you might not realize they hadn't actually given their opinion much thought beyond memorizing the highlights. The recurring theme is that the tool avoids using their own judgment, sometimes even failing to acquire an ersatz opinion; instead just seeking approval. The tool is an open field for anyone who would like to use them for their own purposes. When they choose very poorly, it is obvious to most that the tool has been manipulated and was foolish to have allowed it. Usually singular in actual usage, but sometimes phrases like 'tool shed' or 'hardware store' are used to refer to groups seen as clearly lacking common sense.

One who lacks the mental capacity to know he is being used. A fool. A cretin. Characterized by low intelligence and/or self-steem.

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.

someone who tries too hard. a poser. one of those chic's who holds the sign saying "Carson Daly is Hot." the asstard who goes to a rock show because they heard one of the songs on the radio or mtv. or someone who insists on wearing velour sweat suits. Avril Lavigne.

someone who is a complete idiot/ one who is used by other people, and usually dosen't even realize it/ someone who can't think for themselves/ an asshat.
