This is when you have to fart but you pucker up and the fart travels back up your intestines. This is also known as the inner fart as it is called by monks. They go through a sprititual process where they eat beans and deny themselves the pleasure of farting. This has killed many that have tried.
Cans of beans were once required to give a warning in regards to fart recalls. The FDA established that anyone who is too stupid to fart should probably go ahead and die.
Man did you hear her stomach? I think she just had a fart recall.
Monk1: Is bob meditating?
Monk2: Yes he just ate a large can of busch beans.
Monk1: Wow he is going to have a huge fart recall. How spiritual......
