Similar to a tree burl, a large protrusion typically from the middle of a pizza slice to the crust. A pizza burl often makes a slice undesirable as the portion covered by the burl has no sauce or cheese.
Bro, you said there was a slice left in the box, but that slice has a pizza burl on it, no one wants that dry air pocket slice with no cheese!
