Top definition
A factor that must never be forgotten during a public robbery. This is when a bystander, clerk, or other person tries to be a hero by pulling a knife, gun, or any other way of attacking the robber. The robber must never underestimate the hero factor, which could be deadly.
Are you kidding me!? You want to rob a GYM!? Don't forget the hero factor, my friend.
