The icicles that hang off the edge of a building that could break off at any moment and skewer you from above.
Hey! Look up, and watch where you are walking! There are HUGE death-cicles up there! With even the slightest breeze they could break off, and kill you!

An abnormally large icicle that forms into any shape resembling a giant spear, upside down sword, or other object of deadly shape and size, that when it eventually falls could cause serious physical damage to a person or property.
A Deathcicle totally broke off from my roof and impaled someone the other day, it was huge!
