Derived from an incident in World of Warcraft where a level 70 shamen cast a HOT on a mage as Nightbane was landing, causeing the mage to draw agro and instantly die. Followed shortly by the same shamen being out-healed on the healing charts by his earth sheild on the tank. And to top the cake of fail off, when the he finally died, the raid leader told him to anhk, to which he replied what is that?
It's very rare to come across someone who warrents the label "Bulsora Fail", but when it happens it usually comes right after someone is called an Epic Fail, and the rest of the community is not satisfied with that title.
Rashima "You do know you lose durability everytime you die from a fall, dont you?"
