From the dictionary.

Tool

1.

a device or implement, esp. one held in the hand, used to carry out a particular function.

From another dictionary (for dimmer lights who don't really get the point when it is suggested that they gtfo):

Tool:

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
