Chan charan chan is the Spanish speaking internet's sung version of the classic dun dun dun suspense sting, written out as it sounds. This version is tied to a Simpsons moment credited to Skinner and Homer, which helped the phrase spread as a soundboard clip beyond the episode itself. In posts and edits the chant signals that something dramatic is about to be revealed, even when the reveal is trivial. Its popularity comes from that mismatch, and from how easily anyone can quote, type or replay the rhythm.
