The oyakodon at this restaurant is delicious with its soft, runny egg.
noun
parent-child threesome
Vulgar slang referring to a sexual threesome involving a parent and their child. The term is a crude metaphor based on the dish name. Not used in polite conversation.
そんな下品な話はやめてくれ。親子丼なんて冗談でも言うな。
Stop that vulgar talk. Don't even joke about a parent-child threesome.
From 親子 (oyako, 'parent and child') + 丼 (don, 'bowl' or abbreviation of 丼ぶり donburi, 'rice bowl dish'). The name refers to the use of both chicken and egg in the dish.
