'Shuā píng' literally means 'to brush the screen' — a vivid metaphor where 刷 (shuā) suggests rapid, repeated action like brushing or swiping, and 屏 (píng) refers to any digital screen (chat window, comment section, live stream feed). It describes the act of flooding an online space with many messages, posts, or emojis in quick succession, often overwhelming other content.

This term is widely used in informal digital communication, especially on social media, live streaming platforms, and group chats. It can be neutral (e.g., fans celebrating together), playful (flooding with emojis), or negative (spamming to drown out others). While originally internet slang, it’s now common in spoken and written Chinese among younger speakers and even appears in mainstream media reporting on online behavior.
