armpitties 

When a girl is on her back naked and her titties fall to the side and reach her arm pits

I hooked up with girl last night she an an amazing ass but the worst set of armpitties.

Armpitties 

Breasts (male or female) that originate from the armpit region instead of the chest where they should be. Not limited to folds under the arm- often times, the areola will be there too. Occurs on older big women, natural asymmetries and botched boob jobs.

Bryon: "Dang, that girl has armpitties!"
Kim: "And that's why she can't put her arms down!"

Only weirdos practice armpitting.
