look up any word, like trill:
 
1.
A person whose life is video games, so much so, that they might as well be banging them. gamebangers are usually overweight and live there moms, or are 13 year old boys who think girls are icky. gamebangers rarely sleep, which makes them a little bit grumpy, giving them a deep-seeded hatred for noobs.
gamebanger: get away from me noob!

noob: go make love to your xbox you gamebanger.
