Roastie is an noun used to describe a woman whose genitals have somehow magically mutilated into an entirely different shape, resembling a sandwich, due to her having multiple sexual partners.

It is primarily used by men who don't understand vaginas- often because they have never seen one.
John: That female had sex with someone who isn't me! I bet she looks like a chicken sandwich down there from all the Chads she's fucking! Roastie slut!

Jenna: That guy uses the term roastie unironically. He clearly doesn't understand anatomy, or is even trying to.

An incel or r9k term for a woman who is not a virgin, based on a fundamental misunderstanding of how female anatomy works. They believe that a woman's labia somehow stretches when she has sex, although miraculously this only happens if she has unmarried sex with different men. The word "roastie" indicates that they think elongated labia look like roast beef.
That femoid rode the cock carousel so long, she's become a roastie. I am totally disgusted by her - why won't she have sex with me?

1)An affectionate UK/Ire/Aus term for a roast potato, or

2)A slightly derogatory but humourous term referring to expansive female genitalia that causes near-catastrophic levels of cognitive dissonance in many empowered educated but hysterical female journalists and feminist bloggers, at once labelling it sad and pathetic but also threatening and dangerous, as they do with the general incel culture.
