Yet Another Stupid Death (also Yet Another Annoying Death; Commonly abbreviated to YASD or YAAD) is used when a player has done something, usually avoidable, that leads to his or her demise. Common YASDs include:
- Hitting a floating eye in melee combat
- Touching/eating/otherwise manipulating a cockatrice or its egg
- Drowning in water or lava
- genociding oneself
- Eating rotten food after recently praying
- Eating your pet
Some players distinguish YASD from YAAD, using YAAD for random, unavoidable events such as falling onto poison spikes (provided the pit wasn't already known, of course), and reserving YASD for pilot error.
