Shotgun beer

Shotgun-BeerA Shotgun beer describes the process of drinking a can of beer very quickly.

I studied for my degree in England and the USA and the reason I chose my specific degree was nothing to do with the subject matter, it was because I wanted to go to the USA to learn how to shotgun a beer. 
I can honestly say that living in the States and learning how to do this was one of my favourite experiences.  I also learnt how to do an upside down tequila slammer and thankfully, in spite of my party lifestyle, I did pass all my exams.
