Buzzfeeder hgrant just posted this collection with the comment, "Apparently gay men will only drink beer if it's low in calories, because you know, they totally don't want to get fat."
To me, it looks like the same "party on, dudes" and "you're gonna get laid!" tropes we're used to in lowbrow beer marketing. Except this time, it's dudes getting laid by other dudes.
Welcome to the world of beer marketing stereotypes, my gay friends. Party on.
