Spamming is when someone uses the same technique over and over again in a fight.
Characters are generally insulted for spamming which is viewed as a negative thing. However from looking from a perspective inside of the manga there shouldn't be anything wrong with it. From a perspective outside of the manga we should blame Kishimoto for making a character spam because it is boring. But from a perspective inside of the manga obviously a character is going to spam if it is effective. Sasuke isn't going to say "I could win with Amaterasu, but I did that last time. Let's spice things up a bit, I'll use lion's barrage instead." Kishimoto should arrange the fights in a way where the character wouldn't spam in order to make the fight more exciting.
