The crispy crust that forms on the outer layer of smoked pork products (i.e. babyback ribs, pig butt & pork loin). If prepared properly, pig bark is without a doubt the best part of a pig.
"Mmmmm.... Pig Bark"
"Yo Matt, rip me off a piece of pig bark!"
"You crushed those ribs TZ, but are you gonna eat your pig bark?"
"Check it out, I peeled off all of the pigbark from the pork butt and made myself a pigbark sandwich"
