For another example, body odor is that yucky smell that clings to you when you get sweaty. Sometimes we abbreviate "body odor" as "B.O." It's pretty gross, but a shower can quickly get rid of the odor.
And deodorant helps a lot, too, to stop body odors. Deodorant fights odors: it's a product you apply to your body that stops you from being stinky, or odorous.
Just like we deodorize ourselves, we can also deodorize fabrics or even the air. If someone smoked a cigarette inside your car, you'll have to deodorize the seats to get the odor out. If your kitchen is full of cooking odors, you might have to open a window to let the odors waft out, or spray a deodorizer into the air to kill the odors. Here's Sheldon deodorizing his kitchen.
Can you think of any foods that have an odor: a strong, bad smell? I can think of onions and garlic. Garlic has a strong odor, but I like it! How about you?
