A Fuzzy Musket - Sitting your butt on someone's nose while they're asleep and

Sitting your butt on someone's nose while they're asleep and letting out a stink so bad it wakes them up.

My brother did this to me while I was taking a nap and I smelt like a garbage can.

My friend did a fuzzy musket to my mom and she yelled at me for hours.

During a movie, my classmate did this to the teacher and the whole class laughed.
