A gentleman's cock that is really rather rancid.
A not so charming character by the handle of Corrin who stinks up an otherwise great mecha anime channel with his dirty hands.
Corrin! You're a rancid mancock and when you die I'm gonna jerk one off over your grave. Even in death you'll still be a filthy jizzbitch. Oh don't cry! I love you really...
The unnecessary and mysterious pocket covering the crotch in men's underwear, usually tighty-whiteys. Useful for holding whatever men may wish to keep close to home.
Girl 1: I tried looking for tight and sexy underwear for my boyfriend, but I couldn't find any without the manpocket!
Girl 2: I love a man who wears a manpocket.
The total awesomeness of a single male in a large group of people. To become a "man cock" you must do something totally freaking awesome, and have it recognized by the group of peers. Once given the "man cock" status one can only give it away, it can not be taken. The "man cock" can give full rights to the title of "man cock" or just a temporary pass to the "man cock" title. One is "man cock" until he gives it away to the future "man cock".
