Don't treat an anecdote on the Internet like it actually happened. There have been people posting that they had friends of friends in college do this for twenty years. OP never did it but it definitely happened.
In this case it's high schoolers, half of whom most likely have no sexual experience but are fully willing to explore their anal cavity, having access to alcohol but not that much access.
They can get drunk off small amounts of alcohol, but it's such a small ration that they are freezing and destroying their limited amount of beer (which most high schoolers hate) to shove up their butts, to get drunk slightly faster? How much frozen beer can one butt fit? Is it really that much better than holding your nose and pounding it in front of your friends? Are high schoolers really going to parties with beer in their butts to maybe get a buzz of two beers from one butt beer because they only have access to one twelve pack, instead of just telling everyone how they are so wasted instead?
Not to mention the freezing point of ethanol is about -20 F. Just touching beer frozen solid enough to insert is going to instantly freeze surface water. You'd get your buttcicle maybe a quarter of the way in and it's going to start tearing layers of flesh off. I imagine it would make for hilarious fun party times.
As a guy who was gotten to by some male abusers as a child, I was simultaneously laughing uncontrollably and shutting my sphincter like a bank vault door as I read this. Never experienced anything like this before.
