a tool is a guy who is about as gay as you can be around girls. a tool will often become excited for no reason over the dumbest shit so he can look cool around girls. tools will often only be your friend to get to others. a tool is also commonly a douchebag. if you know someone who says every movie they see is "the best movie ever", they are a complete tool and an ultrafag
toolbag: "hey man you want to go hit up McDonnald's later. I could go for like a sweet ass burger. Dude and then after lets go to this sweet party and if it sucks then lets go see transformers cus I already saw it and its like the best movie ever. And if that doesnt go down we can all just circle jerk each other. Fuckin sweet brah"

A narcisstic, egotistical 40 something living in the greater Boston suburbs who drives a faded red Mitsubishi, wears 1980s cotton sweats or parachute pants and tans while lying on a tin-foil blanket generously applying baby-oil and simultaneously bleaching his hair all while thinking he's cool
Wow, Phil- you are such a TOOL!; What a tool! Look at his stupid hair, face, pants and car! Hey Tool! The 1980s called and they want their hair and peroxide back!

One who is, as J.D. Salinger wrote in "Catcher in the Rye," a "phony." Someone who is false, a media whore, a douchebag, and a servant (or tool) or the Man. The best example, the paradigm of tooldom, is Carson Daly, as quite correctly noted above. Other famous tools include Geraldo Rivera, Ryan Seacrest, Tom Cruise, Stephen Baldwin, Tony Danza, Wayne Brady, Tom Arnold, Ben Affleck, Linkin Park, and most ironically of all, Tim Allen.
