I experimented with a couple Halo usernames back in the days of Halo 1/2..."The Pope" stuck for a little while, I made it because I enjoyed seeing "you killed the pope" or something along those lines. Got kind of ghey after a while, so I tried to think of something out. I always like the name Bob, and to make it, uh, different I added an extra b. Then I needed something to spice it up a little bit. I'm the guy who ***** at Halo and thus just commits ******* or team kills most the time, so you can guess where I got the first part.
Cool Story Bro, I know.
I sometimes will either substitute Hitler with Bobb if that username is taken, or just Hitler by itself. Partly because I act like I absolutely despise Jews even though I don't actually lol.
