Jerrys rule of thumb when the genitals aren’t cooperating he busts out the portobello belt to show all the swollen members competition is steep

portabelly 

A protruding lower potbelly that hangs over your belt-line. Used to store the excess food that no human could possibly hold in their actual stomach.

Sam-"Theres no way he could eat six Double Deckers in one sitting!"

Tom-"He is probably holding three of them in his portabelly."

Old Spice Portobello 

When you grease up your ballsack with deodorant and smack it on someones car. Deodorant is best used for the greasy sack stamp thats left behind.

“Man that guy pissed me off”
“Well what you going to do about it Tim?”
“im gonna grease up my ballsack and smack my old spice portobello grease stamp on his fucking car!”

Portabelly 

The man of your dreams, the guy who kicks ass and doesn't take no an answer. Porta stands for Portal, when you go out with him you'll step into a portal of reality that is unrivaled. Belly cause that you gonna eat good hanging with this man. Give him a try, give the Portabelly a slap.

Just had the best experience with a PortaBelly. Man I can never go back to the Pre-Portabelly life
