ballet biscuits

Feet that are sickled or flexed can be called biscuits. Biscuits especially occur during petite allegro.

Look at my ballet biscuits in that photo! I need to work on pointing my toes.

kniddies

the simplified word for knee b**bs.
anyone can have kniddies, but they are common among people with milky thighs & dead people (ghosts).
if someone has milky thighs, their kniddies have the ability of secreting milk.

Teddy: "can I have a drink please?"
Julian: "yes, of course! I can get you a glass of water, or you could have some milk that I took from my kniddies?"
Teddy: "water please, Julian"
