Pirenium 

The moment in time when life was created. Everything that lives has a beginning, an origin in time that caused it to grow and develop into all organic life we have today. The slice of time when organic life began is known as the Pirenium.

NOTE: there is a closely spelled medical term known as the Perineum however they are two very different spellings and meanings.

At the Pirenium organic life was created.

Mario Bros Perenium Double Dip Presentation 

When a white male takes a black magic marker and writes "PERENIUM" between his legs on his perenium. Staring just below his ballsack and ending the word near his anus. The male then dresses up like Mario from the Nintendo's Mario Bros.

After that, the male will go to a sporting event featuring small to young children, such as PAL soccer or baseball. During a bad call by an umpire or referee, the male gets up and takes off his hat. He then waves his hat in the air and starts screaming "Yo !!!" to get everyone's attention. When a large majority then look at the male, usually consisting of the spectators and the children playing the game, the male drops his red overalls and his underwear and then lifts his leg. He points to his perenium with one hand and lifts his ballsack with the other hand while yelling "Perenium, Perenium, duh duh duh". Just as the onlookers start to show discust, the male the sticks the pointing finger into his rectum, pulls it out, then puts it in his mouth. The male then repeats it several times. After that, the male alternates between both until most likely, someone noticing this event takes matters into their own hands. Usually a parent.

I was bored so I dressed up like Mario and went to a local soccer game at the school and performed a Mario Bros Perenium Double Dip Presentation. After I was badly beaten, I was arrested and I need a lawyer.
