Mastropaolo 

Mastropaolo typically an Italian male, almost godlike due to his sculptured appearance and masculine facial hair. Women want him for themselves, guys want to be him. The usual penis length ranges from 11 to 13 inches. Also, a master in any trade you can think of. Usually a starting athelete. Usually goes for the hottie in a group but from expirence realizes the hot ones usually have the most problems, which then found the formula of finding out which girls are bitches and which ones they can stick their dick into for eternity. If you find a mastropaolo, don't pursue, if its meant to be, he will pursue you.

Example 1:

Girl 1: omg Susie, do you see that sexy man over there?

Susie: yeah I've been staring at him all night. But he's a mastropaolo, so I'm waiting for him.

Example 2:
Rick: look at that dude. Makes me want have an absence of dick so I can be with him.

Ricks gf: I know what you mean. Mastropaolo's do fuck so good. (looks over at Rick and starts crying)
