A motha fuckin' beastly penis. If this term is used towards an individual, it is in the utmost respectful matter or in a very very derogatory sense. This gargantuan pecker is said to be a monster cock of at least 18 inches when limp! Truly, there is no need to be insecure for the said individual. It is a gift, really. The recipient is very well-endowed.
Guido came into class on exam day and whipped out his Italian Stallion. He then proceeded to slap the hell outta us with his 18 inch monster cock in the face until our noses bled and we had red welts all over. It was sick. He then forcefully shoved his staff of doom down all of our throats until we choked and died. It was unbearable.
