expression, godan verb (-ru)
to be in deep trouble; to be in a real mess
Slangy, idiomatic expression for being stuck in a very bad situation. Often used when things have gone seriously wrong and escape seems difficult. The 'ドツボ' part comes from 'どつぼ' (mud pot or trap), emphasizing a deep, inescapable predicament.
