A fat person who tries to make it seam like they are ripped and so strong in front of other people. Often they attempt to down on others that are ripped like no ones business and have no body fat by saying "I'm bigger than you I could break your bones" but the truth of the matter is that the fat tool is coated in fat and attempting and failing to disguise it as muscle until they make the fatal mistake of taking off there shirt for the whole world to see that there "muscle" fails at life and is very limited and hiding under a thick layer of fat.
example of a fat tool:
kid: dude how much can you leg press and how many crunches can you do in a minute?
ripped kid: Yeah I can leg press 600lbs and 150 crunches in a minute on a ok day
fat tool: no you can't your too skinny you have no muscle
ripped kid: Dude your a fucking fat tool, thats all fat you loser you suck at life *shows fat tool and kid cut 6 pack* weres your 6 pack fat tool? Oh thats right you don't have one you fat tool all you have is a big fat keg!!!
fat tool: *Crying* I wish I was ripped like ripped kid! *Runs off Crying*
