Chi shi la is a well-known crude insult in Taiwanese Mandarin, written 吃屎啦, used online as a deliberately over-the-top put-down rather than a serious threat. The (台) tag marks this version as carrying a Taiwanese accent, which meme pages often prefer for extra comedic bite. Clips like this circulate as sub-second reaction sounds on soundboards, in gaming chats and in short-form edits where a fast insult sells the joke. Its staying power comes from brevity, everyone instantly gets the hostility, even without speaking Chinese.
