"Gunner" in its true sense is really more synonymous with "A-hole". The folks who study hard and do well, and sit in the front of the class with their multi-colored pens, are often the furthest thing in the world from a gunner..The gunner sits in back, helping no one, wondering how he can succeed by putting up impediments to others. You don't want to be a gunner. Being a gunner isn't cool. Working hard and getting A's is fine, but not gunnerism.
See I disagree. I've always heard the term gunner used to mean someone who had, in general, have lost their perspective in some way, and particularly when they develop a bizare concept on what is and is not a personel failure. Being a gunner can make you an A-hole (since losing a sense of proportion would tend to promote D-baggery), but you can be a gunner without being an A-hole. You can also still be a good student, even a very hard working one, without being a gunner.
Examples:
Person who studies 15 hours a day: not necessarily a gunner. Could just be a regular guy who wants Ortho.
Person who studies 15 hours a day, is at the top of the class for every test, and often publically complains/cries because they are so far behind: gunner
Person who worked hard to get a 250 on the step 1 and is proud of it: not a gunner.
But if that person tells you they're miserable because they're furious at their terrible performance: gunner
Person who works hard and shows an interest on rotations: good student
Same person berates their peers for failing the team when they take their alloted day off: gunner.
Note that in none of these situations is the gunner actually getting ahead, even in they're own mind, because of their actions. They have just completley and totally lost perspective on what is average, and have come to react to being anything less than the absolute best of the best in the same way that most people would react to a diagnosis of pancreatic cancer. Obviously backstabbing is one annoying behavior this can promote, but that's not actually necessary. Many gunners are actually quite willing to help others, provided you can put up with them refering to grades two standard deviations above yours (and above the mean) as 'below average'.
Three hours every single day as an undergrad is a ridiculous amount if you ask me.
No wonder so many people are shocked by medical school work loads. I went to an engineering school: anyone who didn't study 3 hours a day was either a last semester senior, a genius, or setting himself up to fail out.
I remember about half of the people at football games brought their Calc books for halftime. It made for really embarassing ESPN footage.
