Yea, you can make a lot of words rhyme that normally don't, just by how you pronounce it. It's easier when you're singing though....Slightly Stoopid does it quite a bit in their songs.
No one word rhymes with orange but nobody said you can't use two words. Door hinge, that's a good one. Also bar binge, when you're going out bar hopping. Or star binge, when Britney Spears does it. Or star fringe, where Britney's headed. Tar singe, when you burn yourself with hot tar. Car dinge, when your car's dirty. More?
orange and door hinge have two completely different "o" sounds...For me, anyway oooor. o. Crap, theres no way to spell out the way i say orange
