汝伤臀，臀痛也，非腹也

Meaning

A new nickname for Bilibili by some of its users. Recently Bilibili's app keeps updating, increasingly resembling TikTok which Bilibili users once said "even dogs wouldn't use." Even more humiliating: after users adapted to short videos, ads started appearing more frequently. At this point, B站 users understood Chen Rui (CEO)'s "deep intentions" and began shouting "Bilibili Lite, XXX" in every short video ad that allows comments to vent their frustration.
