Like all great comedy it is about location and timing.

So somewhere you can trap a fart? Great for a stinker, perhaps get one caught behind the door of a supermarket chiller cabinet. My brother used to “cup” people by farting in a suitable receptacle and sneaking up behind them and jamming it under their nose. He still might, although I suspect his wife has probably had words about setting a bad example for the kids.

If you are amongst family or friends then a real ripper seems the correct choice. Everyone can give it a heart cheer but you are also setting a bar that you are challenging other people to beat.
