A derogatory term for a female vagina whose vulva appears larger and darker than the rest of her genitals, resembling the roast beef in an Arby's sandwich. This term is typically used by incels to imply that a woman is a slut or a whore.
Despite the fact that too much sex doesn't make a dick smaller, many men who get their sex education only from porn claim that too much sex makes a pussy worn out and look like Arby's roast beef.
