What does this lyrics mean? Hi, following the lyrics of All star by Smash Mouth, I had some points that I didn't quite understand, I had marked them in braces like (bla bla), can somebody give more explanations on these sentences? Thanks. Somebody once told me the world is gonna roll me I ain't the sharpest tool in the shed She was looking kind of dumb with her finger and her thumb In the shape of an "L" on her forehead Well the years start coming and they don't stop coming Fed to the rules and I hit the ground running Didn't make sense not to live for fun Your brain gets smart but your head gets dumb So much to do so much to see So what's wrong with taking the back streets You'll never know if you don't go You'll never shine if you don't glow [Chorus] Hey now you're an All Star get your game on, go play Hey now you're a Rock Star get the show on get paid And all that glitters is gold Only shooting stars break the mold It's a cool place and they say it gets colder ( You're bundled up now but wait 'til you get older ) But the meteor men beg to differ Judging by the hole in the satellite picture The ice we skate is getting pretty thin The water's getting warm so you might as well swim My world's on fire how about yours That's the way I like it and I never get bored [Chorus x2] Somebody once asked could I spare some change for gas ( I need to get myself away from this place ) I said yep what a concept I could use a little fuel myself And we could all use a little change Well, the years start coming and they don't stop coming Fed to the rules and I hit the ground running Didn't make sense not to live for fun Your brain gets smart but your head gets dumb So much to do, so much to see So what's wrong with taking the back streets You'll never know if you don't go You'll never shine if you don't glow
