2B像皮
[2b xiàng pí]
It plays on words with '2B', possibly derived from a personality description or internet slang meaning immature behavior ('like a fool'). However, when written similarly to English, '像皮' sounds somewhat close to ‘skin’, thus it humorously connects being silly (2B pencil lead looks like graphite) with human attributes, suggesting an unconventional yet fun-spirited self-description.
