A guy who usually can't make up his mind and is unsure about decisions. His personality is very odd and he seems almost bipolar. He is angry, then happy. Mad at someone, then suddenly forgets. These characteristics are much like a woman's on her period, but yes, he still is a guy yet not neccessarily gay.
That guy is such a Mangeena, acts like he's PMSing everyday.
