A shortstack has recently been used to defined a female subject which has the characteristics of pancakeness on her body. In other words, she has pancakeass as well as a pancake, or flat, tits. Saucer nipples would not modify this definition but would be a great +1.
Ey shortstack! You wouldn't wear shoes if you had no feet right? Why are you wearing a bra and panties?
Damn, I think I got a splinter from that shortstack.
