Similar to pancakes, but used in the context where a man is a "tasty food" for someone generally in the sexual sense or the homosexual sense. Never meant to include or imply any form of cannibalism. A few antonyms are things like Mancandy, or Manbiscuits and Gravy.
Jenna demanded a taste of my mancakes! I was happy to allow her that luxury!
When a large (fat) man loses weight, he will lose his Man-boobs. The result will be sagging man breasts known as MAN CAKES. (Similar to a flat-chested woman's PAN CAKES)
My God, did you see that dudeover there with the tank top on? He really needs to wear a bigger shirt to cover up those MAN CAKES he has.
