What means the 'mother father gentleman' - PSY, gentleman

PSY released a music video "Gentleman" on April 12th. You can see it on the YouTube.

So many people curious to know about the lyric, especially the 'mother father gentleman'. Even though the song is korean, but Korean people doesn't know the meaning, neither (and I'm a korean). It's not Korean, yes, it's english.

So the media asked to PSY, after finished his own concert on April 13th in Seoul. PSY said, "That's right what you think". That means you can take it on your own. Someone take it as 'mother fu**er gentleman', and the others get it as 'no means' and so on. It's up to you.

Here comes the lyric translated to English. It's not the official. The song 'gentleman' has not that serious message, it's just for fun with dancing. So please just relax and enjoy it.

PSY gentleman, mother father gentleman
