I mean "gay" as in "completely wussy".You know, as in "dude, that is soooo gay".
You wouldn't catch David Allen Coe or Johnny Paycheck back in the day singin' a song about going to a bar for a drink but instead settling for a glass of milk and a lecture from a preachy bartender. And if they did, the song would end quite differently, like with some lead in the bartender's butt.
