To give or be a victim of a Dutch Muffin is when you or someone else sits on another's pillow and farts. As you stand up the pillow "breathes" in all of the surrounding flatulence. When your victim lays their head on their pillow the fart is expelled directly in their face... Delicious!
Me: Did you enjoy the Dutch Muffin i left for you last night?
Victim: Yea thanks, you ass. It tasted horrible!
