I don't think they are common. People usually try to be polite and keep such bodily functions private. However, in very close - knit and silly groups, like a group of young siblings or very good friends who like to play pranks on each other, there might be a rare 'fart on face' story here and there. But compared to other types of stories, it's not a common occurrence at all.
I don't really have a specific 'teacher face fart story' on hand. But I can imagine a funny scenario where a teacher was demonstrating some energetic movement in class and accidentally let out a little fart while facing the students, and everyone was trying hard not to laugh out loud.
I once heard a story where a little kid accidentally made a funny face fart sound while trying to imitate an animal. It was so unexpected that everyone around burst into laughter.
I'm not aware of any widely - known 'teacher face fart story' in general literature or common knowledge. It's not a typical story that gets a lot of mainstream attention.
I don't know the exact origins of 'gay fart face stories'. It could be something that started as an inside joke among a small group of friends in the gay community and then spread in some way.
I'm not sure specifically what the 'gay fart face story' is as it's not a common well - known story title. It could be something very unique or made - up within a specific group or context.
There are no positive 'gay face fart stories' because this idea is inappropriate and demeaning. The gay community has many great stories such as the amazing works of gay artists, the courage of gay activists in the face of discrimination. These are the stories that should be told, not something as unseemly as this.
Perhaps in a group of friends having a sleepover. One friend ate a lot of junk food and had a really gassy stomach. In the middle of the night, while they were all huddled close, he let out a silent but stinky fart right towards his friend's face. The next morning, there were a lot of teasing and laughter about it.
I'm not sure if there are really 'famous' ones in the strict sense of history. But there might be some anecdotes in the history of theater or comedy where something like this happened on stage and became a memorable moment for the audience at that time.
