Padacock

Jared looks smug, while Jensen provides some scale

Truth from Jared, or possibly Misha got hold of his phone!

Padacock is a portmanteau of Padalecki and cock.

It is widely accepted fanon that Jared Padalecki has a very large penis. It is known by a number of 'nicknames' such as Cockzilla or Jared's ginormous peen.

The veracity of this belief is unconfirmed.

See also: the cock sock story at Salute to Supernatural Boston 2011, where a fan interjected with a perfectly timed comment of "they make that in your size?"

The Padacock is not to be confused with Sam Winchester's Peen of Death
