‘马虎’ literally combines the characters for ‘horse’ (马) and ‘tiger’ (虎), evoking an image of two powerful, unpredictable animals—suggesting a careless, hasty, or slapdash attitude. Though the etymology is folkloric (linked to a legendary painter who sketched a tiger’s head but a horse’s body), the term now functions almost exclusively as an adjective meaning ‘careless,’ ‘sloppy,’ or ‘inattentive.’ It describes behavior where someone rushes, overlooks details, or fails to double-check work.

This word is commonly used in everyday spoken and written Chinese to gently criticize or self-deprecate—e.g., when forgetting a name, making a calculation error, or submitting incomplete homework. It carries mild disapproval but not harshness; calling someone ‘马虎’ implies they’re capable but momentarily unfocused, not fundamentally irresponsible. It’s rarely used in formal documents but frequent in school, family, and workplace feedback.
