Warlike, I agree. But aggressive doesn't have to be a bad thing, if it's spelled out
how they're aggressive. They could like friendly contests of strength (wrestling, boxing, and other very physical sports could be very popular among them), and they would be more likely to be the one to start something happening than wait for someone else to do so--this could be anything from starting a fight to being the first to try out a new dish at dinner.And, as
@DND_Reborn mentioned, they could very well have a philosophy incorporating wisdom into their strength, because mindless aggression is pointless and self-destructive. And in order to keep the aggression from being toxic, orcs could be quick to anger, but also quick to forgive as well--they may get riled up easily, but they lose steam just as fast.
