Deodexed is like decompiling the application (java..etc.) and recompiling it at the same time so that the apps will work even without the .odex file. Once your rom is deodexed you can modify the look of your phone, like adding custom theme for example. this is AFAIK.

If you have a stock rom (original or update), it's not deodexed, unless it is indicated when you downloaded it.
