look up any word, like tinder bombing:
The defintion of someone who is worse than a tool. Used to show great toolness; the tool that holds tools. Use with great brevity as to not dilute the meaning.

A Completely Useless Person.
-This goes far beyond being a so called "tool"...at a least a tool, the object itself, can be useful. Whereas a Toolbag is completely Useless apart from Holding 'tools' Itself.

-Kind of like designing a shovel that would stand up by itself,...instead of a person standing there "holding the shovel up" and watching the other person working.

-A Meat-Head
Are you going to do something besides stand there like a toolbag today?

Hey, Toolbag!?...

What a complete Toolbag.

That guy couldn't punch his way out of a wet paper bag he's such a toolbag.
