Definition: Aggro is an adjective clipped from the word, "aggressive." Aggro normally describes negatively a person who is aggressive in the water, maybe dropping in or yelling obscenities in the lineup. Folks can get aggro on land as well. You often see aggro people who vandalize cars or start fights at parties. But aggro can sometimes (uncommonly) describe an insane (unbelievable) maneuver in a positive way.


If a guy just throws a sick blast over a shallow reef, he might be termed "aggro." Aggro is, however, most often a negative word and is generally muttered in disgust.

Also Known As: salty, gnarly, psycho

Alternate Spellings: agro

Examples: That aggro guy in the red trunks is dropping in on everyone. He is a kook! (OR) Good lord! Did you see that aggro guy in the red trunks pull into that huge close-out? That was sick!
