Wikipedia: Pulled pork
Pulled pork is a method of cooking pork where what would otherwise be a tough cut of meat is cooked slowly at low temperatures, allowing the meat to become tender enough so that it can be “pulled”, or easily broken into individual pieces.
 
Poultry is referred to as being “shredded” as the meat tends not to require slow cooking to be separated from the bone. “Pulled Chicken” has been used to sell chicken burgers and other products due to the premium tag associated with other such tough meat “pulled” for consumption.

I hate making pulled pork. Playing tug of war with a pig for food seems unnecessary.

“I’ve always wondered what ‘pulled’ means,” I said, playing along. “I keep envisioning a frantic tug-of-war between a butcher and a screaming pig, with the butcher always winning.
