Internet gonads. The increased level of bravado shown amongst members of a chat room or internet forum. This allows the members to say things to one another that they would never say face to face, for fear of getting their asses whipped.
Man I ran into Yourcarsux69 the other day and I was just about to run up and kick his ass. But then I was surprised to find out he is actually not such a prick like he is on-line. I guess he just grows a pair of internads when he logs onto the nets.
