| Hint | Nickname | Character |
| Dr. Cox uses this nickname from the first episode on. It refers to JD's fresh status at the hospital. | |
| Kelso uses this as an one time insult for JD's very enthusiastic question answering. | |
| Much to JD's horror, Danni says this to him in the bedroom. Most likely a nickname for a part of JD, rather than him as a whole. | |
| The nickname Janitor came up first when he decides to find JD a nickname. | |
| Kelso calls the males this nickname and the females 'sweetheart'. | |
| Jordan constantly (and purposely) forgets JD's name. She replaces it with this similar name. | |
| Janitor created this mouthful to mock JD's tendency to create nicknames instead of remember actual names. | |
| Carla is the only one to use this term of endearment for JD | |
| Dr. Cox says this to JD as a conclusion to his speech about the medical concept of a zebra. Like all of Cox's other nicknames, it is meant to belittle JD. | |
| Molly insists on calling JD this in spite of his frustration. | |
