Basically somebody or something that is ordinary, not unique, and boring. Kind of like anything vanilla flavored, which you see everywhere. Somebody or something with no personality to it.
Girl 1: It’s so sad that Miles didn’t go for you who’s intelligent, funny, sweet, and pretty and instead went for his vanilla ass girlfriend.

Girl 2: I know! It’s like the only things embedded into her are “I love you Miles” and “my boyfriend Miles...” She has no personality or brains whatsoever
