The Slutty Cat Hos or the Pussycat Dolls or whatever they're called have a song called "Loosen Up My Buttons", and I just wanted to ask if I was the only person who wasn't familiar with the act of loosening buttons.  I have always referred to it as unbuttoning or undoing my buttons.  I wouldn't call it loosening because I didn't realize that buttons could be tight in the first place.  Am I alone in this?
