She really isn't, but Park Ji Yoon's song is titled that way, and she dresses both like a man and a woman, in a bizarre music video that sounds as catchy and bizarre as it looks.  It just makes me think that zombies should be popping out any moment and dancing all funky.

Several years ago, a friend of mine forwarded me some Asian music videos that usually told some sort of story.  Some of the videos were brilliantly filmed just like the style of Asian drama, and in this case, with a bizarre twist to it.  I found the Korean to English translation to this song here: http://www.jpopasia.com/lyrics/20488/park-ji-yoon/i-m-a-man.html   The lyrics itself is about being the opposite gender but in a resentful tone and is a familiar theme to some American pop songs you might have heard from Beyonce's "If I Were A Boy" and Ciara's "Like A Boy."  Park Ji Yoon's "I'm a Man" was so catchy and so weird, I couldn't help but keep listening to it over and over again, even though at the time I didn't understand what it all meant.
