When a gamer doesn't do something on the game that they are playing but instead asks why they couldn't do that certain thing and how they do that thing to the point of mashing random buttons or to the point of questioning the game's development.
This usually makes the person watching angry.
Game: PRESS Y TO OPEN THE DOOR
Gamer: OMFG HOW DO I OPEN THIS DOOR?!?!!? *mashing random buttons until the door opens*
Viewer: I swear, this guy has so much gamer's ignorance.
