A phrase evoked by weebs in reference to their preferred bust size. The quote originally came from the Lucky Star anime, but the origins are mostly forgotten by the people saying this line. It is occasionally used to refer to real life women, but is most popular in the anime community.

This term is currently in a strange place, where any anime girls who have flat chest are regarded by the community as "loli", regardless of perceived age or maturity. This results in anyone who likes flat chests being called a lolicon, who are increasingly being thought of as pedophiles. Due to this new popular perception, use this phrase at your peril. Or do what the rest of us do, and don't give a fuck what people on the internet think about your favorite size of oppai.

Used as a defense when someone calls you a pedophile for liking "underage" anime girls, or loli. Can also be used when arguing about what breast size is best, uncommon though.
Person 1: Dude she looks like she's 12

It's true though. Flat IS justice, anyone who says otherwise clearly doesn't get the appeal. And no I'm not trolling, I am for real. I don't care if not a single man in the world shares my preferences, flat is justice and that is a fact. This is my unwavering conviction til the day I die, so be it!!!
Imagine liking bouncy, buxom, full-figured breasts, like ew. Flat ass and tits are MUCH more elegant looking (not too flat tho). Flat is justice.
