Someone who is a total jerkface. Someone who is so totally full of themselves, that even THEY know it. Basically, just a blubbering bafoon. Can also be used as a term of endearment amongst close bros.
Example #1
Bro #1: Dude, that guy is a freaking hoiner! I can't stand him!
Bro #2: I know! He is so full of himself! Let's kick the crap out of him!

Example #2
Clos Bro # 1: Dude! You are such a hoiner!
Close Bro #2: Thanks! I love you too man!
