paff
When a girl gets off by herself and it sounds like a cat being tickled with a feather but also like a battle cry.
My sister said 'paff' and then I knew she was doing her thing in the bathroom.
At the mall, I heard a girl say 'paff' and I knew she was going to beat me in the video game.
My friend’s dog started barking like a crazy person after he said 'paff'.
