香港中英夾雜字典

定義: Purportedly to have originated from the name of a disposable diaper, this is a code-mixing term that native Hong Konger use as a euphemistic way to refer to a person's buttocks, which is very appropriate to say when talking to toddlers.

用法: E.g. 唔好曳啊，曳就打PAT-PAT (Don't be naughty, or else I will hit your buttocks)

同義詞: 屁股
