We referred to DC Comics Crisis on Infinite Earths here while discussing the Smallville TV series. Now we should refer to it again while discussing Alan Moore's Jerusalem.
"A jackboxer from the Manhattan saltbogs of 5070 had managed to bring down a young ichthyosaurus with his whorpoon..."
-Alan Moore, Swamp Thing: A Murder Of Crows (New York, 2001), p. 85.
"...barbed and ornate wolf-killing 'vulpoons'..."
-Alaon Moore, Jerusalem (New York, 2016), p. 970.
A "vulpoon" is not the same as a "whorpoon" but the coinage was sufficiently similar to make me reread Swamp Thing. Both are future weapons. Jerusalem, astonishingly, moves into what we call the future although ghosts can walk there.
