Meaning

From former famous Bilibili creator and streamer 12dora, nicknamed "Boss," "12," or "Knife Bro." During Bilibili's early commercialization, 12 was one of few large creators doing in-video ads without official partnership. After disputes, his account was banned. He once brought huge traffic to Bilibili's gaming section and helped team members gain followers. The meme "心如刀哥" (heart cold like Knife Bro) emerged from this.
