European pilots will say they have a frozen ATP. They think it sounds better than saying they have a commercial license and have passed their ATP writtens. Their writtens used to be valid for a longer time than the FAA writtens and the ATP writtens count for the commercial license so they would get their commercial with just a couple hundred hours and say they had a frozen ATP. The ATM written is valid for 5 years now but most FAA pilots still seem to take the ATM written when they are getting close to the checkride.
