I tease my self about my "lack of boobs" more than other women tease me...
Saying things like:
"Quit picking on the flat chick"
or if someone is staring in our direction...I would say... "Oh! They are just trying to find my clevage...it will take awhile."
"In 20 years...mine will still be perky, while yours are going to be sagging fun bags."
Sometimes around women it is easier to use yourself as a butt of a joke other than someone else, because depending on the day or the mood, they might not think it is so funny...or take it personal.
