Short For Graduate.
A student who was just finished university and has entered the working world with their irrelivant degrees such as Media Studies or Aroma Therapy. Grads appear to have good book smarts, but lack common sense and social skills. Grads are usually rather unbalanaced and are prone to falling and stumbling over there own feet. Grads are usually found at the student bar getting pissed or attempting to boil eggs in a kettle at there student flat.
Grads usually have Double-Barrel names which just sound stupid and made up.
E.g. Timothy Dooflap-Heaton
