Debadge is when you take the badges off (like grand prix gt/gtp/se and the 3800 V6)
Its reallllllyyy easy!(and makes the car look a lot cleaner) Take a heat gun or hair dryer and some fishing line or dental floss (make sure to wear gloves so you dont cut your hands), heat it up and slide the floss or string between body and badge and walllaa.
Then I took a eraser wheel on a drill and took the left over adhesive off. You can also use other stuff to remove the adhesive...but Im not sure what is safe or not safe to use on the paint.
