Carefully place the pork butt into the slow cooker.
Cover with the barbecue sauce.
Cover with the lid and cook the low for 6 hours, carefully remove the lid and shred the pork with two forks.

Notes
This can also be done in the Ninja Foodi with this Ninja Foodi Pulled Pork.If preferred, you can prepare the pork with the rub and let it sit overnight as well in the fridge, then get it out in the morning and let it come to room temperature for about 20-30 minutes before continuing with the remaining instructions.
