Hey Everyone, i'm new here!

A few weeks ago i heard the begining of a song on the poor sound system at a basketball game...

It was a rap song i think with a guy's voice (couldn't identify the artist). The only lyrics i could gather "sounded" like, "Get your finger up" May have been finger(s) but not 100% sure... Who know's what it was! LOL

If you happen to have a piano etc., i can give you the beat LOL

It goes...

F.....F F F.....F#.....C,...........F.....FFF.....F#.....C,. ...............over and over again kinda fast?

If anyone knows the name of this song, it will make me so happy!!! LOL Thanks a million!
