Pennywrink is an abbreviated way of saying Penis Wrinkle. It is meant to be a new insult for a new decade. Think about it like this: As "douchebag" was to the oughts, "Pennywrink" is to the teens. It can also be shortened to "P-dubs" if needed.
That bar is filled with Pennywrinks, I don't know how you can stand it.
