friceps 

The large fat deposits on the underside of the upper arm achieved only through regular near-daily consumption of McDonald's French Fries.

Her friceps were so large, the Macy's parade attendants put a patch on her shoulder and tried to re-inflate her underarm.

Fat triceps. The floppy fatty back area of the upper arm. Usually caused by not exercising or just being plain fat.

Damn, the lady in the checkout line had some big floppy ficeps...she should NOT be wearing a tank top!

Fryceps

The unsightly, batwing like fat that develops where the tricep muscle should be. Often seen in lazy, obese individuals who eat large amounts of French fries.

Blair has been hitting the McDonalds hard lately. His Fryceps are gett'n swole!
