逗比妹子哒哒哒
[dòu bĭ mèi zi dā dā dā]
In a funny way of expression, it means a cute or silly but cheerful girl ('Dada' in the end just expresses an exclamatory, cheerful mood) . Generally speaking, those calling themselves this name are outgoing and not afraid of making a fool out of oneself, they're usually fun to be around
