sewer systems aren’t air tight either - they need to let gasses escape, so i think even without an airtight seal if we consider a sewer in general a pipe system of this category it’s fair to consider the connection between butt and toilet also part of this system
many people have a special wireless connection, which explains the sewage that spews from their mouth
I’m not sure you’re supposed to form an air-tight seal around the toilet bowl, but if your farts are that bad then thank you for your consideration
