look up any word, like basic bitch:
 
43.
Gaming lingo that refers to types of enemies or NPC's that aggro as a group instead of one at a time. Refers to the circular perimeter around enemies that determines whether or not they aggro. Some enemies in RPG's aggro as an entire group even when only one is attacked. Useful call-out for RPG players who might put their team in danger by aggroing a group of enemies instead of just one like they planned. See aggro definition for examples.
"Don't attack those pig-wolf looking things, they're halo'd!" or "Everyone get ready, I'm gonna aggro that halo of spider-monkeys". In the second example, the word halo means both a group of enemies and a group of enemies that all aggro at the same time.
