Mine goes back to the time I had just signed up to my first isp , man that was a while ago .
On the home page was an Aussie Rules tipping competition with great prizes that interested me enough to join.
Since it was the first time I had used a username on the net I put in my initials but was rejected , so added numbers to my initials and each kept getting rejected as being taken , so I jumped to 45 and bingo , since then it's been my name on steam , psn , live etc I also use it has my character name in games .

My real/nickname.

Good thing that you used such a powerful name , not a weak one like that loser Kim possible.

That's a badass name 

Ohh I played my first 7th gen shooter. Quake 3 I think?? And I saw Wh1pL4sh. Then for the second part of my name, I was subscribed to XBL. So... L1ve

It's a play on Pauline (my name) and Pollinate (I love bees and honey :3 )

I pretty much use this name everywhere nowadays :P

For your honesty I decided to rename you 

Now everyone will know!

Invisible cat doodoo.

I've answered this at least 5 times since I jave joined, but basically I am obsessed with the game Roller Coaster Tycoon similar to a drug addiction, so RCT are the initials of the game and junkie is my addictive status
