Substitute arms
the flabby, wing-like flaps on the bottom part of a woman's upper arms; that every time they wave or write on the board the skin flaps in the air. (most commonly seen in the education field)
Mrs. Clark has HUGE substitute arms. Every time she writes out the Pythagorean theorem on the board , I'm scared they will knock me out in the back row!
