Remove pork roast from crockpot and shred with forks (this will be very easy).
Drain juices from the slow cooker, reserving two cups of liquid. Return pulled pork to the slow cooker. To the reserved liquid add the brown sugar, hot sauce, and crushed pepper flakes. Stir well. Pour over shredded pork and place the lid back on the crockpot.
2 tablespoons brown sugar, 1 tablespoon hot sauce, 1 teaspoon crushed red pepper flakes
Place on low or warm setting until ready to serve. Can be made ahead of time, refrigerated, and reheated in the microwave.
