The mound of pubis fat that completely engulfs one's genitals when they reach morbid obesity and resembles the dorsal region of the orange gourd. As made famous by American comedian Louis C.K.
"Holy Shit! Did you see that fat bastard on the Rascal? He had the biggest pumpkin top I've ever SEEN!... this week." Yes America, drop the Cheetos and jump on a treadmill you fat fucks.
