A very annoying person to be around, due to the fact that they are very smug and always have to win at everything, no matter how meaningless. A slamxmega will spend almost all of their time locked up in their dark, damp, and most likely moldy room playing bad Sonic the Hedgehog games and listening to Justin Bieber. When approaching a slamxmega, take caution as they have a tendency to projectile vomit upon initial contact with another human being.
Guy 1: So I went over to Paul's house yesterday, and when I opened the door to his room he puked all over my new shoes!
Guy 2: Yeah, he's a total slamxmega now, he's really into all those crappy Sonic games.
