Tool 

A Tool is one that proceeds to lack the capability of understanding he/she is a dumb ass. Others may think of a tool as one who jerks off randomly with such a fast motion, that you wonder to yourself, "how do they still have skin left?".

Addison: Ya i know! He is a tool by definition for sure!

Tool 

1) A tool is a member of society that often acts like a complete moron without realising. At the time of acting like a moron what they are trying to achieve is a humour factor! However they do not achieve this and end up looking like a "tool" to everyone but in their minds still believe they are a god, when really they are not!

2)A tool can also be someone who tells blatant and obvious lies in front of people that know the truth therefore the same moron outcome takes place. Lies may include:
- The stealing of a persons joke and telling it in front of them and still claiming it as your own
- The amount of girls you have slept with
- Things you get up to on the weekend

3) When you get more than one "tool" or a collection of "tools" this may be refered to as a "toolbox" or a larger group may be called a "toolshed"

"Why are you lying about something we all know is not true you TOOL?!?!"
"Those 2 belong in a toolbox"
"YOU TOOOOOOOOOL!!!!"
"Some of the people i hang out with make me feel like im in a TOOLSHED!"
