怪兽别跑biu媳妇别闹bib
[guài shòu bié păo biu xí fù bié nào bib]
An interesting expression mixed with internet slang that combines elements of playfulness, intimacy, and endearment towards people, such as partners and children, implying keep still for both monsters/children and spouses and just enjoy this moment now please. 'Biu', 'bib' are sound onomatopoeia. It has a funny and lighthearted nuance.
