满瓶不动半瓶摇

Meaning

A joking way to say someone is done for or about to die. "Starting the banquet" (开席) originally means the feast at weddings/funerals has begun, but as internet slang specifically means "the funeral feast is starting" = "about to die." Example: "If food doesn't come, I'll start the banquet" (If I don't eat, I'll die)
