差一点就是萌比
[chā yī diăn jiù shì méng bĭ]
A '萌比' (mengbi) refers to someone childish in terms of being naively cute or adorable; however, it can often be used jokingly in a derogatory way among Chinese netizens. This username shows someone who is not entirely, but almost reaches the level described by this slang term, which adds a humorous tone.
