A group of guys in sleeveless UFC shirts and fauxhawks that are either talking about their gains, saying they're swolemates, or drinking protein shakes.
Too bad you can't see yourself in any mirror at the gym because there's always a toolbox blocking it.
The term "toolbox" refers to someone who is such a tool that his supreme stupidity is on the level of what you'd expect from a collaboration of several tools. When someone is this many tools in one, he is a toolbox.
When someone is so dense and pathetic that they are not just a tool, they are an entire toolbox. Toolboxes have a tendency not to think for themselves. Toolboxes are prevelant in frats and sororities, oh and politics.
