Back in my younger days, we used to get those shorty Miller bottles and "shoot beers". You open one up, set it on a table, put your hands behind your back, lean over and grab the beer with your mouth only, kick your head back and down it in one gulp.
When I was in high school, a classmate kept a cooler of Gluktstite (I think that was its name) 4 ounce cans in his car in the school parking lot. He'd drain a couple for lunch and show no sign of drinking in the afternoon in class.
