Forehams 

The arm equivalent of cankles. These occur in nature when you view an individuals arm, and where their forearm ends and their hand begins is not clearly defined. Generally occurs in obese individuals.

The origins of forehams is similar to cankles. The words "forearm" and "hands" were concatenated, creating forehands. Except when said quickly, it sounds like "forehams", and clearing having hams is the right way to go when naming obese body parts.

Phyllis was so fat her legs had cankles and her arms had forehams. She looked like a bowling pin with four hot dogs sticking out.
