How it's used

This term carries a casual and slightly irreverent tone, similar to calling someone the old man. It is strictly for informal speech among friends or peers and should never be used when addressing one's father directly or in formal settings. Using it in front of elders or in a professional environment is considered highly disrespectful.

Common phrases

Common mistake

Do not confuse this with 老竇, which is the correct character for the slang term meaning father. Many people mistakenly write it as 老豆, which literally means old bean, though this character is now widely accepted in casual text messaging.
