Glava-Smech is the term given to a specific form of mutation J'avo experience where the head forms itself into a set of pincers. As is typical with J'avo mutations of this type, Glava-Smech mutations can be experienced alongside other mutations to the arms and legs. "Glava" and "smeh" (pronounced "smech") are the Serbian words for "head" and "laughter", respectively.[1]
