A man who wanders gyms nationwide and looks completely ridiculous. He has biceps that are just ridiculously disproportional to the rest of his body, which causes him to not be able to fully extend or lower his arms. A slam pig has little to no social skills, and communicates only through grunts and glares. Occasionally, the slam pig will wander out of the gym until he realizes that he is unacceptable in society, and must rely on the gym for shelter.
Mr. Man is always at the gym when I am there...he grunts at the gym folk and he looks RIDICULOUS...he appears to be gentle but you never know...you never know with a slam pig...
