Someone who refuses to accept being inferior in any situation. Often incredibly boring, continuing to ramble on in an attempt to prove any supposed superiority, killing the mood in any social situation. The person will exaggerate a small triumph, refuse to accept faults and only focus on any perceived strengths. Will challenge anyone to a competition to prove superiority and will invariably lose.
