‘翘腿’ literally means ‘to lift (qiào) the leg (tuǐ)’ and describes the physical action of crossing one’s legs—typically by resting one ankle on the opposite knee or thigh. Though 翘 can mean ‘to raise’, ‘to tilt’, or ‘to curl upward’, and 腿 means ‘leg’, together they form a common, colloquial verb phrase used to depict this relaxed or casual sitting posture. It is frequently observed in informal settings like homes, cafés, or waiting areas.

The expression carries neutral-to-slightly-informal connotations: while not impolite in everyday contexts, it may be considered inappropriate in formal situations (e.g., job interviews or official meetings) or when sitting across from elders in traditional Chinese settings. It is often paired with verbs like ‘坐’ (sit), ‘躺’ (lie down), or ‘靠’ (lean), and commonly appears in descriptive or narrative writing to convey posture and demeanor.
