Someone who sucks Ivan Balls

Those who suck Ivan balls

Gameness 

It is a determination to master any situation and never back down out of fear. Something that you must be born with, it can't be taught.

Thanks to his gameness, he took control of the fight when it went to extra rounds.

gamenesia 

The act of returning to a game you haven't played in an extended period of time and having completely forgotten how to play, how your abilities work, what you're supposed to be doing. or all of the above.

Person 1: Man, it has been so long since I last played World of Warcraft that I have no idea what I'm doing.

Person 2: sounds like you've got a case of gamenesia.
