history
Earliest form 称帝称王 traces to Cao Cao's 让县自明本志令 ('Edict on Returning Counties to Make My True Intentions Clear'): 设使国家无有孤，不知当几人称帝，几人称王 - 'Without me, who knows how many would have proclaimed themselves emperor or king.' The Song poet 汪元量 then used 称王称霸 in 读史 ('Reading History') and the modern form stuck.
register
Always derogatory - describes someone who acts like a tyrant in a small arena (a workplace, neighborhood, school, industry). For an actual ruler dominating a region, 霸 (bà) is closer to 'hegemon' than literally 'king.'
