Hunkeler Joseph/Wolve
From 3rd ID Wiki
In 1994, while participating in an online AirWarrior 2 Squadron, "The Muff Divers", his Captain requested that Hunkeler change his callsign from RedLumpRamRod to Wolve. Hunkeler did not dispute the request, as his callsign was intentionally immature and disgusting, but Wolve seemed to fit.
Wolve is not a word, but is derived from the plural word Wolves, and the singular word Wolf. The word is unique because it forced a plural word into a singular word, and it was never contested or noticed for seven years.
