Very muscualr calves on a man or woman, usually unproportional with the rest of the body.

Gignormathighs (gi-norm-a-thi-ghs) When some ho walks her huge ass-thighs down the stairs and her gigantic, cottage cheese thighs are giggling their way along, you can say, "Damn, those are some gignormathighs." When some bitch has thighs wider than her hips, you can wonder, "How do those calfs carry those gignormathighs?" When some fatty waddles her way across the cross walk and her thighs are jiggling like jello, you can scream, "Contain those gignormathighs!"
