I thought the video of the girl farting in the subway train, which I posted a link to earlier in this thread, was going to be funny.
It was weird.
Most of the animated fart fetish videos I saw on YouTube were weird to say the least. Some of them were taken off of YouTube, I presume because YouTube thought they were too inappropriate.
No all fart fetish videos, especially animated ones are/were intended to be dirty. A number of them are supposed to be comedic.
As I said, I didn't even know fart fetishism was a thing until I watched an episode of Web Soup
in which they talked about weird fetishes, a couple of years back.
