Haha, I definitely make up stupid names for my classes based on puns that my brothers always yell at me for having. A class with the Scar-H and tactical knife? Scar Tactics. A Class with the Barrett .50 Cal? 50 Calorie Diet. A running class made up of the UMP and USP? Mind the P's and U's. It's a totally pointless aspect of the game but can be really funny if you enjoy it, be creative.
