a penny whistler
A penny whistler is a fart so loud it could make a cow jump out of a barn.
During the family dinner, my uncle's penny whistler was so loud it made my dog run out of the room.
At the restaurant, my friend's penny whistler was so bad the waiter came over and asked if we needed a fan.
During the game, my brother let one rip and the whole team started laughing and the game got paused.
