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.
Or...someone has simply made a better argument and the “bullied” loser resorts to armchair psychology.
