在唠叨用嘴堵住你
[zài láo tāo yòng zuĭ dŭ zhù nĭ]
This means 'Shut up by covering your mouth', reflecting an exasperated feeling toward incessant talkers, or perhaps used affectionately between close friends/partners, where one jokingly silences another physically. Might also convey mild annoyance while still showing fondness at the same time.
