Plug assemblies for plugging a wellbore tubular and methods relating thereto are disclosed. In an embodiment, the plug assembly includes a central axis and a seal sub including a plurality of axially extending fingers and a tapered outer surface. In addition, the plug assembly includes a sealing element coupled to the axially extending fingers of the seal sub. Further, the plug assembly includes a slip sub including a tapered inner surface, and a plurality of axially extending fingers. The fingers of the slip sub each include one or more teeth. The seal sub is configured to be at least partially inserted within the slip sub so that the tapered outer surface engages with the tapered inner surface, and axial advance of the tapered inner surface within the tapered outer surface is to radially expand the fingers of the slip sub to engage with an inner surface of the tubular.
