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.

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

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

A guy who acts normal around people he knows/is used to but gets loud and starts acting like a douche (similar to a peacock in mating season) when around, but not limited to, attractive women. This can also apply to women but that term would be defined as shecock.
Last night Phil saw this hot chick in Starbuck's and he was about to make his move on her until this total douche came along and started being a peacock. Needless to say she ran off and he was left watching bestiality mongoose porn again...
