“Coed” as a noun informally/imprecisely refers to female college students (for reasons that I have no idea, as it seems like it should be a symmetric label to me, given that a coed college requires both men and women, but the use of “coed” as a noun overwhelmingly means women).

“Cherry” suggests virginity.

I’ve never heard of CoedCherry until this HN post, but from the name, I’d assume they were an adult site focused on college or college-age women.
