Placing one's hands on their genitals (primarily used by males) for warmth in cold weather.

The term comes from the idea that the Polish will put their hands on a car muffler to stay warm.
My hands were frozen at the game the other day, so I did a Polish Muffler.

Jane: You must have been freezing, it was -10 out there!

Dick: Yeah, I saved myself with a Polish Muffler.
