American drinking culture. Or more so american culture affected by drinking.
I guess they sell a ton of beer cheap that’s usually passed out quite freely at parties. So much so that in many parts of the country you are a pariah for being a non-drinker even in religious parts. Don’t drink because of your religion, pariah. Can’t drink because of health reasons, pariah. Afraid of relapsing back into alcoholism, pariah. Seen a ton of people stumble around drunk all the time and it put you off drinking, you’re still a pariah for not chugging one down.
Cheap beer fuels rural american culture which is why those folks who love to call anyone who lives within a minute of a Starbucks a snoflake had a massive meltdown over her pushing bud light.
