Brittney Griner: I'm Proud Of My Tiny Boobs ... So Stop Body Shaming Me!!

Brittney Griner wants the world to know she's proud to be a member of the I.B.T.C. ... taking to social media to smack all the haters body shaming her for a lack of boobage.

It began when Griner posted a picture of herself in a cut off tee shirt which exposed a little side boob. It wasn't enough side boob for some ... and she was clowned in her comments section for cup deficiency.

Griner swung back with her very next post ... putting up a partially nude image of herself and an accompanying caption addressing anyone who has an issue with her girls.

"I love being naked and I don't care people seeing this bird chest of mine and making fun of it! Go head! I love myself and I love my body!"

Good job Brittney ... we would say A for effort ... but we don't want any beef.
