how about these?
in view of some recent "heavy metal" rock icons departing this mortal coil, I propose:
Philtyium
Kilmisterium
Wurzelium
Lynottium (as it's 30 years to day that he died)
(for non-rock fans, these relate to 3 now deceased MotorHead band members: Phil "Philthy" Taylor, Ian "Lemmy" Kilmister, Michael "Wurzel" Burston and the late lamented Phil Lynott of Thin Lizzy).
