Not literal mommy gf
(Not literal) mommy gf is a meme that originated on r9k and is a variation of the ideal gf meme. The meme generally describes a woman that is loving in both a romantic and maternal way. It is a common fantasy among incels, however such women are extremely rare in real life and the few that do exist are very unlikely to date an incel. Incels who desire such a woman typically do not have an oedipus complex, hence the "not literal" part.
