意味

A crappy boss — a blunt, vulgar complaint about a terrible, incompetent, or toxic manager.

クソ上司 is a raw, unfiltered expression of frustration about bad management. While クソ (literally 'crap/shit') is vulgar, pairing it with 上司 (boss/superior) has become a common venting phrase on social media, in after-work drinking sessions, and among close colleagues. It encompasses all types of bad bosses: micromanagers, credit stealers, harassers, or the simply incompetent. The phrase's popularity reflects widespread frustration with management quality in Japanese workplaces.
