A measure of one's ability to play extended fast sections in Guitar Hero and Rock Band before before becoming utterly exhausted and not being able to finish the song.
"I can't make it through Raining Blood - I can nail the main section for the first thirty seconds, but then my vision begins to narrow and my lips begin turning blue."
"Dude - sounds like you need to work on your Guitar Hero endurance."
An ability that one gains after hours upon hours of gaming, of not needing to eat. While in Gaming Endurance state, one cannot perform simple daily tasks like taking out the trash without loosing the ability and feeling hungry again.
Guy 1: Dude, you've been playing WoW like 10 hours straight, aren't you starving?
Guy 2: Nah man, I got Gaming Endurance. I can go on for 10 more without breaking sweat..
Hey Garrett, that chick may not be the girl of your dreams, but she does have the endurance package so you won't have to worry about breakin her before your done.
