[Rihanna]

(verb) To create hostility in others, causing them to attack you. This is frequently seen in MMOGs (massively-multiplayer online games) when a player draws the attention of one or more hostile NPCs (non-player characters) and is attacked by them. Also seen is the chain agro, where the hostile NPC who was agroed causes the next nearest NPC to also agro on the player, setting up a chain reaction.

The name of Wanders--the main character--horse in [Shadow of the Colossus], significant if only because the AI engine that dictates his behavior is, by far, one of the most complex and realistic animal behavior engines to date. The horse is not without its eccentrics, however, and is prone to rather confusing responses when you issue him commands.
