They are the epitome of… oh, how do you kids say it… #friendship goals? Every post under that tag could be used to describe their relationship, including recommending actual internet porn to one another along with a blunt list of reasons why it’s good porn. Not even smut fiction. Actual porn. I’m not sure whether I should be jealous or appalled, frankly.
Honestly, if no one actually KNEW any better I would say those two were dating. They are pretty dang close but I guess you could just say they have a very close platonic love and relationship.
Seriously though, anyone who DOES want to date them might have to go through the other first, not to mention get ALONG with the other.
