Gunner

A medical student that tries way too hard by keeping up with daily medical news, read medical journals on the toilet, and brings all their notes to the gym while "working out"

SC: Did you know that Ezetimibe (cholesterol lowering drug) is CI in heart disease? It said so on AMA-news this morning.
JY: What's Ezetimibe? Dude what a gunner!
