‘懒猪’ (lǎn zhū) literally means ‘lazy pig’ and is used affectionately to tease someone—usually a close friend, family member, or romantic partner—who is being sluggish, unmotivated, or reluctant to get out of bed or start a task. While pigs are often stereotyped as lazy in Chinese popular culture, the term carries warmth and familiarity rather than real criticism; tone and context make it playful, not insulting.

The compound combines 懒 (lǎn, ‘lazy’) and 猪 (zhū, ‘pig’), where 猪 functions as a vivid, slightly humorous metaphor—not referring to actual animals but amplifying the lighthearted teasing effect. It’s common in informal spoken Mandarin, especially among young people or within families, and rarely appears in formal writing. Like many Chinese pet names, it softens reproach through cuteness and shared intimacy.
