I use to believe that the lyrics of the song 'kick a little' by Little Texas actually said 'you've go to kiggle-it and cause a stir' instead of 'you've got to kick a little'. The fact that the song was named kick a little never struck me. It wasn't until I was a Junior in college and singing in my car with all my friends that I was corrected...and really embarassed...personally I think kiggle-it-up sounded better anyway!
