Hawkstache 

A mustache and chin patch facial hair combination that true Seahawks fans (12s) grow out during the playoffs for good luck. A hawstache is dyed green and blue for the super bowl but only if the hawks make the big game. A hawkstache must be shaved off the day after either a playoff loss or super bowl Sunday.

Dude. Did you see Matt's hawkstache?! It is FREAKIN' RAD!

Halfstache 

1) Half of a moustache and/or beard. Preferably the left half is kept and the right half is shaved.

Dude, the halfstache is the most innovative thing of our time. It looks sweet!
