A large man of half Italian and half Puerto Rican descent whom has genetalia that is the size of a coffee can, hence the name "Sanka". This man can commonly be found driving an Acura TSX around the state of New Jersey looking for "large" women to have sexual relations with. He may also be found doing extremely fast bunny-hops and 180's on his Eastern Ace of Spades BMX bike. He also enjoys eating his moms homemade stromboli while searching for shemale pornography on the internet.
