A term used for a woman, commonly a thot or slut, who has slept around so much, her vagina is so loose and used up, it is claimed to look like roast beef. These are commonly the single mothers or the women who have lost their looks coming back to their friend zone male companion who they shot down over and over, but are now ready to settle with said companion since no one else wants to loosen their vagina up any further. Therefore, the woman and the male friend settle, rather than fall in love, based on fear of loneliness.It's a term that offends SJWs, thots, sluts, and third-wave feminists, causing them to cry out "incel" without realizing that incels are "sex workers" greatest fans (See CheeryCola) or take the term personally and go into the natural anatomy of a woman (See Cringe With Carro ) to try and gain the moral high ground when there is none to begin with, as roastie and incel are both negative terms.
