Cherosie is the femslash ship between Josie McCoy and Cheryl Blossom from the Riverdale fandom.

Canon
It's not mentioned how long they've been friends, but from what Josie says she's got Cheryl's back whenever, although they really appear more to be a power liaison. Both have strong stata in the high school social hierarchy, and Josie recently joined the cheerleading squad The Riverdale Vixens, likely without an audition, probably due to her relationship with Cheryl. They are both power brokers and live in the spotlight, Josie actually requesting to be the center of attention if she's to stay with the Vixens, while Josie's a bit annoyed at Cheryl wanting to perform at Pop's with The Pussycats, but allows it all the same. When Cheryl's drugged and almost raped by Nick St. Clair, Veronica, Josie, Melody and Val all come to her rescue and Josie cares for Cheryl.

dangerous liaisons Cheryl thanks Josie for being there for her, saying that's why she's pushing for Josie to get a record deal through a contact Cheryl gave the tape of their 'Milkshake' rendition to. Meanwhile, Josie's getting creepy 'secret admirer' teddy bears with notes like 'I'm watching you' and her mother's getting death threats which involve Josie.

After spending some time with Chuck Clayton, who has changed his behaviour, Josie receives a box with a pig's heart and a drawing of her saying 'if I can't have you no one can', prompting Josie to allow Chuck to be blamed for it and later told not to be around Josie. It turns out that Cheryl has developed an unhealthy infatuation with Josie and is the one threatening her while trying to eliminate the competition.
