Partisan[pahr-tuh-zuhn]
because it was my favorite weapon in a game called Phantasy Star Online. It also has a literal meaning which is pretty cool:
"Military. a member of a party of light or irregular troops engaged in harassing an enemy, esp. a member of a guerrilla band engaged in fighting or sabotage against an occupying army."
As for the name Callintriph, my other alias was Kaiden, but when I moved on to XBL it was taken. So I made my GT Calintriph back when I first played Halo 2. When I got live a second time on the 360, I couldn't remember my info so I added one "L" to the name and I've used it since 2005-ish.
By the way awesome thread.
