Somebody who frequents internet message boards and chat rooms and tries to project an image of being a badass. Typical internet tough guy behavior may include:

- Claims to be a master of any number of martial arts styles.
- Claims to be incredibly strong and physically fit.
- Threatens violence against other message board members or chat room users who anger or annoy him.
- May claim to an ex-Marine, ex-Special Forces, or gangsta.
- Makes exaggerated claims about his own sexual prowess and ability to seduce women.

Most internet tough guys are liars, and are actually angry, socially-awkward young males who use the internet as a place to act tough because they can't pull it off in real life.
Examples of comments an internet tough guy might make:

"If I knew where you lived in real life, I'd kick your ass for saying that."

"The other night I beat the shit out of some dude who dissed my Harley. I then took his girlfriend (who happens to be a Victoria's Secret model) back to my place and shagged her until the sun came up."

Someone who writes/comments on youtube videos/forums and argues with other people or insults other people with extreme confidence (confidence that they normally dont have) due to the anonymity of the internet.

If you tell someone fuck you in real life, they might kick your ass.

If you tell someone fuck you on youtube, they can't kick your ass because they don't know who you are. So ppl like to use this absence of consequence to fullfill their need to raise their self esteem.
Dude, look at this guy talking smack like crazy on youtube, internet tough guys... such losers.

Internet Tough Guys are the people who you will find in chatrooms, usually having some sort of badass name (e.g., Gladiatior007.) and an intimidating avatar. They'll contantly be bragging about how they beat the shit out of people and steal their girls or are a professional wrestler and weigh 400 pounds of pure muscle, and they'll often say things like "If I knew where you lived, i'd kick your ass." and other bluffs. 99.999999% of these people are socially awkward, weak people with few friends in real life. They are very easy to troll, and pretending to be an ITG is also a fun way to troll people.

Someone filled with anger who never had the chance to throw it back on others because he or she is physically inferior.

A.K.A. The result of having been bullied at school as a young child, or simply the result of all IDIOTS out there who are so immature spiritually that they can't bare having the truth said to their faces.

An overly strong-minded individual who suffered from the jealousy of his inferior peers.
Internet tough guy : "your parents would deserve to be sent to Antarctica for engendering a child they were not ready to raise otherwise than by making him think that physical violence is correct while verbal violence is a sign of weakness"

Internet tough guy "Don't bother answering me unless you agree at least to an extent with me, I don't give out time to lowly minded beings like you and I know you'll only try (with miserable arguments) to proove me wrong because I just put in your face that internet tough guys are your creation, not theirs..."

A feckless, worthless useless human being. A paper tiger. (vulgar) A pussy.
That guy who comments on everything with a decidedly hateful point of view is a real Internet Tough Guy.

One thing about internet anonymity is anybody can use the same anonymity, including people who are not internet tough guys. Tease somebody in person, and say what you're saying online in person, don't be an internet tough guy yourself.
A group of posers called a guy out for being an internet tough guy, but never said any of what they said when they were looking at the asshole.
