A close friend, bro, or hetero life-mate who is always down for chilling, relaxing, drinking brews or chillaxing.

A term of utmost endearment between two people, just short of being completely gay for one another.
Man, I'd take a bullet for you, Justin. You're my one true poopdawg and nothing could end our friendship.
