Nurses feel the need to let people know they are nurses. Similar to name-dropping, a nurse-drop is when a nurse tells you that they are a nurse very randomly in a conversation without the subject matter even being relevant to the topic.
Nurse drop:

Person A: Hey have you eaten at that new restaurant? It's really good...
Nurse: Yeah I've been, it's pretty good. I'm a nurse so I have a distinguishing palate.
