JDelekto: For me, it's doing something in a game which by all means should get you stuck, but finding out the game developers anticipated it happening and leave you with a way out.
One example that comes to mind is the introduction sequence in Half Life where you get off the train at the Black Mesa station and the scientist needs to open the door for you. So before he gets the opportunity to open the door, you wail on him, killing him before he can open the door to get you into the main part of the game.
Of course at that point, several turrets drop down from the ceiling targeting in on you thoroughly peppering you with bullets.
You make it out instead of getting stuck, just not alive.
Play The Stanley Parable. Don't ask questions, don't look up information about it. Just put your full trust in me and play it. I promise you, you will not be upset in any way.
