A Quilhelm
The face you make when your insides are trying to escape through your butt
I did a Quilhelm during my yoga class and my instructor told me to meditate on my pain.
I did a Quilhelm in the grocery store and the cashier looked at me like I was a freak.
I did a Quilhelm in my car and my dog started barking at me like I was a ghost.
