A dick that is literally shaped like a potato.
Most penises, of average girth and length, and traditional phallic shape, resemble a hot
dog with a mushroom tip. A potato dick, on the other hand, is excessively girthy. Typically with a burst of girth in the middle, and the glans of the
penis is smaller than the shaft resulting in it being generally indistinguishable from the rest of the
penis. Potato dicks also tend to have a downward curve, but it is not a requirement.

Will: Holy shit, that dude has a huge pecker!
Bill: Ya...but it's a potato dick, bro. It's like trying to jam a campbells soup can into a donut hole.
