When a girl only dates guys beneath her because the birth control she's on has her hormones so fucked up that she's attracted to the pheromones of weak, feminine men. These relationships typically end after the girl stops taking birth control as she discovers how naturally repulsed she is of her sissy bf after the fact.

Similar to "chocolate-covered raisin" relationships. You could put chocolate on anything — caramel, marshmallows, peanut butter, etc — putting it on a raisin is just insulting.
"Why is she dating that guy? He must be really funny, have a lot of money or a big donkey dick."

"No he's a loser, it's a birth control relationship."
