僻头鬼盖头人
[pì tóu guĭ gài tóu rén]
This nickname mixes a colloquial saying, creating an unusual juxtaposition. Directly translated it's about a ghost covering the head (an odd expression) versus humans doing the same act which signifies an unconventional or eccentric person, someone who acts differently or out of norm but can relate to common behaviors, possibly highlighting the absurdity or peculiarity in behavior in an exaggerated manner.
