I felt the same way. As a black American I thought kegs were something out of a movie too. I had never seen one.

Until my first year of college. I went to the wrong house party, it was a white fraternity. Before I could leave a group of guys asked me if I wanted to do a keg stand. I asked “wtf is a keg stand”? Next thing I knew I was upside down drinking beer. Drunk as shit in like 3 seconds.

Still to this day it’s the most fun I’ve ever had at a house party. And I didn’t know a single person there.

This didn’t answer your question at all. But considering you were asking Americans questions using those weird units of measurement we don’t understand, consider us even. Lol
