look up any word, like dirty sanchez:
 
1.
A person who militantly believes that babies are born to be breastfed, that it's a mother's obligation to give her baby it's birthright through nursing. Strives for education and the destruction of ignorance.
Melissa is nursing her three-year-old, and has boycotted Nestle Corp. for it's formula practices, she's such a boob nazi.

2.
Mothers who think that anyone who feeds their kids formula is an evil child-abuser who doesn't deserve to have kids.
'Excuses' such as illnesses, not producing enough breast-milk, being on certain medications etc are often looked over by the more militant nazis.
Apparently, no Boob Nazi has ever, ever made a parenting mistake. To suggest otherwise is heresy.

For such dedicated parents, Boob Nazis seem to spend an awful lot of time condemning people on LJ, and making user pics of their saggy tits and ugly brats.
"You know that LJ user, bensmommy? She thinks that making baby clothes with the slogan 'formula 4 success' is oppressing the breast-feeding mothers out there! What a boob nazi!"

3.
A term associated with females who refuse to showcase their boobs in public.

Applies to any female wearing clothing that either directly covers their bare, chest region and/or clothing, usually loose fitted or of very thick material, that hides the natural curvature of said chest region.

Can also be applicable to a female whom, after being asked to reveal her boobs, refuses to do so.

Important: The female subject must possess boobs in which one actually wishes to see (i.e. an old woman with sagging boobs would not be eligible for this title).
Boy: Can I take a peak at them titties of yours?
Girl: Oh my goodness, no!
Boy: You're such a boob nazi...

6.
Word coined by formula feeding mothers and used in a poor attempt to insult breastfeeding mothers whose success at nursing causes them to feel guilty over giving up and choosing an inferior food.

Like the word "cunt" (ref: "Vagina Monologues"), it has been captured by breastfeeding mothers and used as a term to describe a mother who cares enough to be passionate about giving their children the best and healthiest start in life.
"Sarah nursed her baby in the restaurant last night and didn't cover up! She's is such a boob nazi!"

The nurses at the hospital after you have a baby that try to get you to breast feed all the time and always tell you that you are doing it wrong.
