萌比萌哒哒
[méng bĭ méng dā dā]
'Meng Bi Meng Da Da' combines two popular expressions: 'meng' (cute) and 'da' (a cheerful sound often used after words for emphasis, meaning nothing on its own but showing endearment or excitement). This username is an exaggerated way of saying the user considers themselves extra cute or adorable.
