a guy who does not under stand he is being used for what he has, that guy who shows up unexpectedly to parties and social events and everyone looks at him like "wtf are you doing here" , a guy who can't make decisions for himself relies on what everyone else is doing to make a decision

An individual who will do literally anything to make themselves look better than everyone else, usually at the expense of others. The tool tries to hide his/her own shortcomings by making others look small. In business, this individual proactively seeks recognition by bragging and exaggerating about his/her achievements and tattling on others who make (usually trivial) mistakes. They have a selfish motive that is driven, not to better the organization or promote cohesion, but instead to enhance their own personal gain by railroading and backstabbing their peers and making their own, usually trivial, achievements stand out in front of their supervisors. This individual is usually a complete jackass whose achievements normally don't stand for themselves without the individual constantly berating others in comparison.
I watched 'Good Morning, Vietnam!' for the first time last week. Wow...that kiss-ass Lt. Hauck really threw Adrian Cronauer under the bus when he found out Cronauer was so much funnier than he was. What a tool!

The word "tool" may be used as an insult, describing someone who is being manipulated without their knowledge - implying they are naïve and ignorant.
