Get the peacockable mug.
A person (usually male) dressing, acting or talking in a way to draw an access amount of attention to themselves usually deriving from a lack of attention as a child, a bit of ego-mania and causing surrounding onlookers to hate their fucking guts.

It's the adult equivalent of saying, "Hey mom, look at me. Look at me! LOOK AT ME! Watch what I can do!"

The peacock can take many forms. This can be a Jersey shore asshole or a hipster fuck. Multiple polos with the collars up or massive ears plugs and tattoos on the neck. The result is the same.
Dude 1: Why is that guy wearing a top hat in the bar?

Peacock with his shirt off: (walks through conversation) Hey guys, you see anything you like??

Guy 1: No. So anyways, my boss says...

Peacock: (rubs nipples) Are you sure you don't see anything you like?!?!

Guy 1: Shut the fuck up, you peacock-motherfucker before I punch you in the dick

Peacocking is the action or actions exhibited in the beginning stages of courting. These actions are typically only temporary and exist during "the chase" of a mate. Much like a male peacock displaying his fruitful colors of his feathers to capture the attention of a mate.
For example, Bob, while dating Jane, paid for dinner, brought her flowers & candy, won prizes for her. However, after confirmation of a mutual relationship (boyfriend/girlfriend) all actions taken to impress Jane are now gone. Ergo, Bob was peacocking. courting dating
