An upper arm so fat that that it is as big as a thigh.

The fat lady was waving, creating a breeze from her thelbow.

Get the Thelbow mug.
Like "cankles" of the wrists. Fat from thumb to elbow. Lack in definition around wrist bones as generally seen in either someone obese or a broken/swollen wrist.
Did you see the thelbows on that guy?

Yeah, it really exaggerates his tiny hands.
