666: Why Bilibili Viewers Type This Number 666

If you watch any skillful moment on Bilibili — a difficult game clear, a flawless drum fill, a chef’s knife flying through a fish skeleton — the danmaku will fill with 666. It simply means: impressive. well played.

Where it comes from

The number 六 (liù, six) sounds like 溜 (liù), slang for “smooth” or “skillful.” Typing 666 is shorthand for “that was smooth/expertly done.” The usage spread from gaming voice chat into general internet culture, and it’s now platform-neutral praise across Chinese internet.

What it definitely does NOT mean

Unlike in Western numerology, 666 has no diabolical connotation in Chinese internet culture — the Book of Revelation reference doesn’t exist locally. Nobody typing 666 under a pancake-flipping video is making a theological statement. It’s closer to spamming “GG” or “PogChamp” energy: pure, uncomplicated applause.

How it’s used

• Volume matters. One 666 is mild approval; a wall of 666s sweeping across at the exact moment of an impressive play is communal awe.
• Variations exist. 6666, 66666… more sixes, more enthusiasm. Some viewers type 三三三 (“three threes,” from 3 = multiple) ironically.
• It can be sarcastic. Context and tone matter — a deadpan 666 after someone’s obvious failure reads as “well that went great.” Sarcasm is usually signaled with surrounding text though; bare 666 is genuine.

English equivalents

“Well played,” “clutch,” “goated,” or simply spamming 🔥 — whatever your community types when someone lands an impossible trick.

When NOT to use it

It’s casual register. Don’t put it in serious discussions, don’t use it to respond to bad news, and know that in formal writing it means nothing. Inside a danmaku stream during an impressive moment? Fill your boots.
