I'm not sure why this comes up so much since normally /co/ doesn't give a flying fuck about Archie, but here we go again. I read a ton of Archie as a kid and I still read it sporadically, so I'll let you guys in on a little secret.
Jughead isn't gay, he just isn't interested in women. You know how Archie is constantly getting into shenanigans because he's in love with Betty and Veronica? Well Jughead has a front row seat to that show every damn day. And he thinks to himself, why? Why get led around by women when all it does is lead to trouble? Wouldn't life be a lot easier if you just left women to be crazy by themselves?
Fuck women, acquire burgers. That's Jughead's mindset.
