Gaggenschtäsh
A head job where the guy grows a pube mustache on the person’s lip and makes them gag so hard they might lose their lunch.
At the party, my cousin did a gaggenstasch on my mom. She started crying and threw up in the punch bowl.
He did a gaggenstasch on me right before my math test. I got a D because I was too busy gagging.
My date did a gaggenstasch on me and I almost choked on my burger.
