Bullying

Bullying is the use of force, threat, or coercion to abuse, intimidate, or aggressively dominate others. The behavior is often repeated and habitual. One essential prerequisite is the perception, by the bully or by others, of an imbalance of social or physical power, which distinguishes bullying from conflict. Behaviors used to assert such domination can include verbal harassment or threat, physical assault or coercion, and such acts may be directed repeatedly towards particular targets. Rationalizations for such behavior sometimes include differences of social class, race, religion, gender, sexual orientation, appearance, behavior, body language, personality, reputation, lineage, strength, size or ability. If bullying is done by a group, it is called mobbing.

Empath: The Luckiest Smurf stories
In the EMPATH: The Luckiest Smurf story series, Hefty subjected his fellow Smurfs to bullying when he was a Smurfling, and has retained that part of his personality into his early adult years when he made the Smurf formerly known as Pushover the subject of his bullying, by getting him to do tasks that he should normally do himself. Some Smurfs such as Empath and Duncan McSmurf have withstood Hefty to his face when it comes to his bullying, and eventually some of his targets have actively resisted.

Hero: The Guardian Smurf stories
In the HERO: The Guardian Smurf story series, Hefty subjected Pushover to bullying since they were both Smurflings and since Hero had been exiled from the village due to the misuse of his newfound Ki abilities. By the time of the Firefly Festival when Panicky had Pushover go to the Great Swamp to light the torch with the Foxfire and had accidentally awakened the Marsh Monster, Pushover felt he had enough of Hefty's bullying and just let him have it for all the years of abuse Pushover had endured from Hefty.
