Short for aggressive or aggression. Can be used to describe how a person is behaving. Also in MMORPGs such as World of Warcraft it refers to an enemy attacking you if you get too close to it. In MMORPGs certain enemies have different ranges that will trigger them to attack. Some enemies can attack even when you are fairly far away and some only attack when your characters is right next to the enemy or in very close proximity. Higher level enemies tend to have a larger range than lower level ones.

a term that has been used for decades by surfers and other water-headed types to describe someone who is overly and unesscessarily agressive, competitive, or assinine whilst in the water. prolonged exposure to the aggro can ruin even the best session, so "deal" with them immediately (read: choke with your leash then return to your state of zen-like calm once they are dead)
Watch out for those SoCal types, theyre aggro, they should stay in Cali where they fucking belong.
