我不是2B我是铅笔
[wŏ bù shì 2b wŏ shì qiān bĭ]
This internet name uses a wordplay in Chinese where '2B' can mean either an internet troll (often labeled 'SB', a mild insult) or the designation for '2B' pencil. It conveys humor by saying “I am not 2B, I'm just a pencil,” suggesting modesty and self-effacement.
