A man-boy monster that lives on the west end of the city of Florissant. He is rumored to have grown a full beard at the age of 14 and has released 14 triple platinum rap albums. This individual is extremely dangerous and must be avoided at all costs. If you sight a grandma billy hold completely still and keep blank thoughts as most Grandma Billies can hear thoughts.
