Rank for sure. Loud farts are funny. Rank are disturbing.

Depends on if you’re withdrawing or depositing

Rank, because it means there’s shit mixed in it. Loud without smell is mostly just gas.

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.

Loud farts are funny, rank ones just ruin everybody’s day
