In the early days on internet gaming, I called my KornKiller... you know.. because it sounded dangerous lol. (Was playing "Descent" at the time, but was in other games as well: Doom etc))
I think I happened on someone else with it, so I changed it to Cougar. Not surprisingly, that wasn't unique enough. A friend happened to use the name Speedy.... but he stopped playing games, and as mentioned.. the name wasn't unique enough, so I robbed him of his username, and stuck it onto mine, because generally speaking I was very quick at the time. So.. Speedycougar came about.
That name lasted into TFC, where I think I held the 3rd place for points/score for TFC on the clanbase for a while. Then at some point I decided that Speedycougar, either resulted in me being called Speedy or Cougar, and it sounded a little childish... so I simply shortened it to Scougar. I have been using the various names for over 16 years now.
There you go... a long boring tale, with no mediation involved.
Although my alternate which I started actually describes me pretty well. MajorFaff.
