Bulldogs: The Bulldogs are Riverdale High's mascot and the school's football team.
Choni: Naturally, this is Cheryl and Toni's ship name.
Chugmo: Perhaps one of the funniest play on words in the show, this is a liquor store chain that almost bought Pop's before the Hiram Lodge stepped in and bought the diner in season two.
Falice: A lot of people want F.P. Jones and Alice Cooper to hook up again, so this is their ship name.
Five Seasons: If you hadn't already guessed, Five Seasons is Riverdale's version of the Four Seasons Hotel.
Fox Forest: This is a creepy forest near Pop's where Kevin usually spent time with his love interests. It's also where the Black Hood tried to kill Moose Mason and Midge Klump and where the Riverdale Reaper massacred the Conway family decades earlier. In recent episodes, it's presumably where the Gargoyle King resides.
