thread elbow
When wearing a large threaded sweater of long sleeve shirt of some sort and after a while with weight on the elbow area, the skin on and around your elbow has thread lines imprinted in it. Usually accompanied with very slight pain/discomfort.
Carolyn: "What is with your skin there?"
Allen: "Oh, it's this sweater, it gives me bad thread elbow"
