There is no clear original source for Fecal Deposit 2.0, and its title appears to be a joke label from a user-generated soundboard rather than a scene from a film or show. It belongs to the same online family as a generic fart meme sound, where a crude noise is reused as a quick punchline across prank videos, reaction edits, and gaming clips. Like a simple fart button, it works because the sound is instantly recognisable, needs no setup, and turns an ordinary moment into a deliberately childish gag.
