McGwire 

A full mustache or 'stache worn in fu manchu style with a goatee, with or without a patch, in the style of former St. Louis Cardinals home-run hitter Mark McGwire.

I got tired of foolin' with a full beard, so I shaved off the sides and turned it into a McGwire.

McGwire 

Originating from old Irish, the McGwire was the village man who always thought of himself as big and grand, when in reality it was much talk. The McGwire would always be hated upon by other villagers.

McGuired 

The ultimate level of intoxication. This happens beyond the blackout stage, and can cause one to do ricidulous, unexplainable things. When McGuired, one often does not wake up in their but, but often on their couch or kitchen floor.

Q: Are you going out tonight?
A: Yeah, but I don't want to drink so much that I get McGuired
