装逼摸摸兜卖萌嘟嘟嘴
[zhuāng bī mō mō dōu mài méng dū dū zuĭ]
A playful combination describing someone putting on airs ('showing off'), then checking their pockets perhaps for courage or resources, acting cute or childish while puffing out the lips in an adorable way. This mix of bravado and cuteness can be both entertaining and self-mocking.
