On the
WoW role playing server "Conquest of the Horde", a guild named Demonifuge had a roll combat system where mages had the ability to cast "Netherwind." A spell that would be an instant
crit upon rolling over 20 but if you
fail, you will end up summoning more enemies. During one of these combat situations, a character named Vandreal managed to cast an AoE (Area of Effect) netherwind and rolled a
19, resulting in summoning a large group of imps. This was a giant
fail and lulz were had. Since then, the act of failing hard at casting Netherwind is now known as "Pulling a Vandreal."
Random mage 1 summons the powers of Netherwind to aid him against the enemies who surround him. He rolls 19.
Random mage 1 has summoned a large group of imps from missing the spell.
Random mage 1 has succeeded with pulling a Vandreal
Random mage 2 comments "Dayum! You just pulled a Vandreal!"
