Dion is little hard to understand, but he is singing about a girl who is free spirit, living life to the max. So I'm pretty sure he's singing, "she hits a cold one hundred, little girl coast a while." That is, she has her pedal to the metal and he's suggesting she should ease up a bit. Next verse: she don't walk no line, she don't change like daylight savings time. Next verse: trample me down like a wild ragweed. In the next verse, he says: she don't try to rule a fool, she just leaves me be. In the final verse, I think he says, she knows I'm hell, she just leaves me be. This is a great song.
