According to Wikipedia: “A shot glass is a small glass designed to hold or measure spirits or liquor, which is either drunk straight from the glass (“a shot”) or poured into a cocktail.” The article goes on to explain that the name is derived from the Germanic poet Shottenspiel, who had a penchant for transitive verbs, and whose tiny head was partially made of glass.

This is potentially a good time to reiterate that you shouldn't believe everything on the internet, and could also be a solid lesson in not doing shots of Wild Turkey all night while climbing deeper into Wikipedia holes instead of getting new products into the store that you ostensibly run like you were supposed to be doing, but someone has to test the product first, right, so maybe just a couple more trials would be appropriate, and I am kind of thirsty still now that you mention it, but maybe you could turn off the lights and stop shouting so I can get this thing in the store after all, also I think there are bats in here so maybe call someone about that and I'll just put my head down for a little bit....
