My PSN ID is really a continuation to my long used username back since 2006 on an Animal Crossing Wild World forum (my first forum). I have pretty much used it where ever it is possible since then. Thankfully no one had used it when I got into the PS3 universe.
Anyway, my PSD ID is a combination of my favorite game along with my name. The name of the game is "Viewtiful Joe", so I just took off the "Joe" and placed the "Josh".
As a kid, I used to watch a bunch of cartoons after school. I liked Mobile Suit Gundam the most.
The funny part is, I misspelled my desired name when creating it, so I ended up with Moblesuit75, missing the i before the l. It actually took me a while to start playing multi player games, and when I tried to have some of my friends request me, I could not figure out why they could not do it. Ha ha, it was because I was giving them the name with the wrong spelling.
There's that, and I though Voltron75 would have just looked weird.
My PSN name came from a movie series that I'm a huge fan of. That series is, Indiana Jones. I loved all the IJ movies. Yep...even "Indiana Jones and the Kingdom of the Crystal Skull." My all time favorite movie is "Raiders of the Lost Ark!!!" So I took the Nuke The Fridge joke and made my PSN name a reference to my beloved IJ films.
