A guy that is a total dick. No matter the time or place, he always seems to be the biggest dickin the room. Tool. A craftsman is guaranteed to be a "tool" for life.
A male in his early twenties who exhibits tool-like behavior such as almost constantly not wearing a shirt, cropped hair, fist-pumping, use of pseudo-ghetto phrases learned from rap, and an affinity for but lack of talent in sports, who seems to be, despite these massive character flaws, an alright guy.
