The origin of this specific recording is not documented, but its appeal comes from everyday Spanish internet humor. Caquita is a softened, childish way to talk about poop, and jsjsjsjaja mimics uncontrolled laughter in Spanish texting, similar to writing hahaha in English. Short clips built on that combination circulate as reaction sounds in chats, edits and soundboards, where a two second burst is enough to signal disgust and amusement at the same time without needing any context or explanation from the viewer.
