The clip comes from a user-uploaded soundboard, where its own description jokes that it is no fart, just a long 'piiiiiii'. That wink is the whole appeal: the file is named like a bigger, better NanoFart, but the audio delivers a squeaky letdown instead of a blast. Meme editors picked it up as an anticlimax button for fail compilations, gaming bloopers and short skits, and its two-second length makes it easy to drop into rapid-fire edits where a full fart sound would feel overdone.
