Im not so sure, should this thread be here or by the funstuff, but anyways :
Im quite sure everyone has done something silly, stupid in real life, while being in a dungeon or a raid. Something, that made you and your group wait and/or die from laughter.
LIke for me the a weird moment was, when we were raiding ICC25 hc mode, I got so excited while fighting the blood beasts,that i accidentally stepped and squished my entire bowl of blueberries, that were right beside me on the floor. And thus I got a new nick - Blueberry crusher .
Maybe you have done something silly, that has wiped the entire group>? (not regular mistakes, but something you could just facepalm about later)
