Medium is Premium
A mantra that is mainly used in the anime/weeb community to voice their preference in a certain breast size. This phrase is in the middle ground of both mantras, "flat is justice" and "oppai is truth." The phrase is for people who don't like massive anime boobs but also don't like flat lolis and instead like average or normal sized breasts.
Shota: Oppai is Truth!
Pedo: Flat is justice!
Normal Person: Medium is Premium!
