来自星星的叫兽
[lái zì xīng xīng de jiào shòu]
This translates to 'Beast Teacher (or Professor) from the Stars', a playful take on the phrase 'professor' or teacher ('called 'beast teacher' online due to its pronunciation similarity). It conveys otherworldliness and intelligence combined with humor. This username was popularized in some online communities, suggesting a mix of academia and extraterrestrial fascination.
