Fanatical Aux Cable Enthusiasts (F.A.C.E.s)
Aux Cable Enthusiasts (A.C.E.s)
Those are the categories currently within the fanbase, although “Auxiclan” sounds like it could be used as a comprehensive term for both A.C.E.s & F.A.C.E.s. I like the current designations, though, because they highlight the individuality of each fan more than a collective identity.
Sometimes a fan’s base is called a “stand”. If this fanbase was named accordingly, we’d probably be a grandstand. (It can mean a stand that’s grand, and it can also refer to a place where a group of fans can sit when they go to an event.) I’m guessing there’s some fanbase somewhere that calls themselves “The Grandstand” because the pun is just too good for no one to use it. “F.A.C.E.s”, “A.C.E.s”, and “Auxiclan” are much more personalized for this particular podcast’s fanbase.
