Now to answer the OP's question and not the porn questions. A roastie is basically a woman who is loose as fuck. Now then why is it assumed if she has roastbeef she's loose as fuck?
Simple really, the more sex a woman has, the more her labia stretch. In fact porn stars are some of the top clients for labial reconstruction surgeries. In today's age where a surgery can reconstruct your hymen, and even give you fat implants for breasts (illegal in the US) it's becoming ever harder for a man to spot a natural, non-whorish attractive woman by appearance alone.
So in recent modern times this ancient as fuck meme which /r9k/ revived for some reason is really nothing more but a tool to get sluts and feminists angry. Because most of these women have really long flappy labias due to their whoring around. Now mind you, not all women are born with aesthetic vaginas, some women unfortunately are born with some really long labias.
These women are usually those who have a lot of testoterone in them. To be fair however, women who have high testosterone tend to be more promiscuous than those who don't. So one could say those who are born with roasty vaginas already have the tendency to be a typical roasty slut.
