Mo lei tau (traditional Chinese: 冇厘頭; simplified Chinese: 冇厘头; Jyutping: mou4 lei4 tau4; pinyin: Mǎolítóu; lit. 'nonsensical') is a type of slapstick humour associated with Hong Kong popular culture that developed during the late 20th century. It is a phenomenon which has grown largely from its presentation in modern film media. Its humour arises from the placement of surprising and incongruous elements, and the complex interplay of cultural subtleties. Typical constituents of this humour include nonsensical parodies, juxtaposition of contrasts, sudden surprises in spoken dialogue and action and improbable and deliberate anachronisms.
