A phenomenon of leaky, aged booty. After a long day or tough day on the stomach, a thin film builds around the anus. Without having taken a poop, you could wipe with toilet paper and turn it yellow from this film. Yellow paper can be treated with a wet wipe, or a shower. Yellow paper smells like actual butthole. It should be flushed immediately, but disposing in the trash or putting somewhere to be found can make a fun prank.
