The act of getting a rediculously large dip/serving of smokeless tobacco normally placed between the bottom lips and gums. As normal consumption of a standard sized dip would normally fit between your thumb and pointer finger (the average serving per can would be around 10); a "fattey" would take at the least all fingers other than the pinky (A "fattey" will empty a can in 3 or sometimes less servings).
Hey Bubba, can I get some of that skoal? Sure uncle dad, just don't get a fattey.
