自我陶醉 is a four-character idiom (chengyu) meaning 'self-intoxication' or 'self-admiration'. It describes a state of being overly pleased with oneself, often to the point of ignoring reality. Although the dictionary lists it as a noun, it can also function as a verb phrase in practice. The literal meaning is 'self' (自我) + 'intoxicated' (陶醉). Note: the correct pinyin is 'zì wǒ táo zuì', but the source data omits the fourth syllable.
