Flash A Hungry Smile Lyrics

Lyric discussion by PiazzaNewYorkCatcher 

I'm pretty sure it goes:

When you walk into the room Girls frown boys swoon

But all you've got to do is do it To know there's really nothing to it

And I know this may sound strange, but I think he's trying to get a girl to sleep with him? He thinks she's gorgeous but she's too scared because he's really keen?
