异类小酷比
[yì lèi xiăo kù bĭ]
This username combines the meaning of being unique and quirky ('异类' means an oddball or nonconformist) with cuteness and playfulness ('酷比' comes from combining '酷' (cool) and sounds like a childlike term of endearment). It suggests someone who's unconventional and likes to present themselves as cute yet different from the ordinary.
