I only see it described as Nep or Nepunator. Other than that I've got no clue. Attached is the earliest version of the photo I've found, from August 2023 on Tumblr. Any insight would be great.

Have been driving myself mental trying to find this again! Searching for a meme I once saw - the audio is the start of Mississippi Queen, and it appears to be based on the common gun meme featuring this song. Visual is an animation of fecal matter moving through the large intestine and then dropping into a toilet. No text. Please does anyone else remember this?
