keyboard tough guy: someone who is needlessly belligerent/confrontational in online settings but is a meek little bitch in real life. Because of poor life choices, a typical keyboard tough guy works a dead end job and lives in a rathole apartment in shitty neighborhood or rent-free with his parents. He is consumed by his jealousy of people who are more successful than him and his willingness to blame everybody but himself for his problems. As a result he suffers from low self esteem and anger issues. In the online world he can a.) raise his self esteem by acting far more aggressively than he would ever do in real life settings and b.) vent his anger by projecting his jealousy, insecurity, and sexual frustration onto others in a non face to face setting. keyboard tough guys tend to use douchey screen names and often make pathetic attempts to sound 'street' in their posts. They also frequently use ALL CAPS (the online equivalent of screaming like a little girl) when berating people. An inordinate number of keyboard tough guys can be found on sports forums (personally attacking people who criticize players or teams they worship) or political forums (spouting off on angry occupy wall street or tea party orientated rants and throwing personal insults at anyone who disagrees with them). When a keyboard tough guy attacks you just troll them right back: they will often run away from an argument they start when another user cuts through the bullshit and puts them in their place .

Some weak ass punk kid who yells shit out at you from the passenger side of their friends car . Usually something like "Pussy", "Fag", "Fuck you", or some other bullshit to make them appear tough. If they were in any real situation where someone could retaliate they would never say such a thing.
