what does the word locomotive mean

I've stood a weight problem all my life. My parents bought me "huskies" while I would definitely grammar school. I wasn't an incredibly active kid. My parents always provided 3 good meals for me daily. School lunches were actually nutritious in those days. They weren't anything as if they are now with pizza, tacos, hamburgers, hot dogs, chips, sweet sodas and many types of kinds of chips and desserts. I hear chips are the main course especially with school girls. Today's kids don't have the opportunity. Karaoke is more popular than ever and countless fans around the world are jumping on the bandwagon which are more popular revolution in personal musical entertainment to come along in decades. After all, who doesn't desire like a famous singer? With Karaoke, even the least talented crooner includes a opportunity for that big "moment" within the spotlight when everything comes together.
