slang Someone, especially a medical doctor, who is authorized to prescribe medication. Primarily heard in UK, Australia. Being a psychiatrist is about a whole lot more than being a pill roller—medication should be the very last resort when treating a patient. You shouldn't go to some pill roller every time you have a cough. You're body doesn't need all those drugs in it.
