Someone who is "too big for their body". They can't do anything without bumping into someone. When they sit down they just flop, most likely bothering the person they sit down next to. People like this are mainly found in public areas, like movie theaters, restaurants, etc. These people are also very ignorant. They sit down behind you at the movies, kicking your seat multiple times, without even saying "Excuse me" or "Sorry". Nope, they just clod their way on through life.
I'm just trying to watch this new movie and some clod kicks my seat 4 times without saying anything.
