Other forms: glamorized; glamorizing; glamorizes
When you make something seem more attractive or exciting than it really is, you glamorize it. Movies you've seen might glamorize camping, but after three days with no shower, you may find it less enticing.
Making anything appear glamorous is to glamorize it. So you can glamorize your dog by dressing him in a fancy velvet collar studded with jewels. It's more common, however, to use this verb for the act of making difficult or dangerous things seem very alluring. A book might glamorize a climb to the top of Mt. Everest (which is actually very dangerous), and an old movie might glamorize the life of a gangster (which was decidedly less luxurious once he was convicted and imprisoned).
