Headset Hero

An online gamer who enjoys talking smack over the headset in an attempt to belittle or intimidate other users. Unfortunately the gamer in question is most often unable (or unwilling) to "back-up" their words with potential action and is therefore referred to as a "Headset Hero"

In other words: The "Headset Hero" is a gamer who will talk like a tough guy on the headset when his anonymous words will likely lead to no repercussions; however in person they are likely the opposite of the persona represented online.

The defined gamer is often easily identified by their prepubescent voice or lack of verbal skills.
