A Caldywelly is usually a PE teacher who can be found to play warcraft in his free time. His students will pick up on this and make fun of him for it. As you can tell, any respect he had, he has lost now. He also has a irish accent that even an alcoholic leprachaun would be proud of. However, after all the abuse, he manages to be a half decent teacher.
'Hey, is that Caldywelly sat over there?'
'Yeah, he's probably playing with his Level 70 elf warrior using the sword of a thousand truths mixed with the art of a true warrior.'
