Puppy fart syndrome is when a person is shocked or woken by their own fart.
I was enjoying a good meal with family and friends when I let out a small cough, but also let rip with a huge fart. This made me jump and quickly leave the room.
I was just drifting off to sleep when I let out a loud fart and woke up startled at the loud noise.
Puppy fart syndrome can happen to us all occasionally.
