My first name - P.T. Flea, is from the movie "A Bug's Life". I was walking through the living room one day, heard the name - it was suggested that I use it online and so I did. I used it for years.
Having been gone for 9 months, I have since requested it be changed to "Two Listen" upon my return. This name, has actual meaning behind it. Over the 9 month disappearance, I moved hundreds of miles across the country and left everything I had behind to be with the girl who became my fiance in May - whom I have known since I was 13. (And met online, no less!) We decided one night that when we got married, we didn't want to keep either of our present last names. We are both different from the rest of our families, we represent something different, something new. And so we decided we should come up with a last name that was different, and new - just like the family we would become on the day of our marriage.
We wanted it to start with an "L", because the character from Death Note is awesome and we think it sounds pretty. We looked up hundreds of different last names and didn't find any we liked - we had limits. We didn't want it to be too common, we wanted it to flow with both our first names, etc. After a week or two I came up with the idea of making it something more than just a name - making it almost a way of life, a constant reminder of that which was important. I came up with "Listen", and pitched the idea to my fiance with the reasoning that if more people listened to eachother, maybe people's relationships wouldn't suck so much. Also that it might keep us both from becoming someone who failed to listen, as everytime we signed a document, sent an email, received mail or anything - we would be reminded to Listen to eachother.
It also is one of the most uncommon last names we could find.
I needed to utilize this that would be our new last name, and so tried to create a new screenname for various things that revolved around it. I live my live in its entirety for her, and I found it important for everyone who knows me, to know this. I also didn't want people only to associate the name with me - because I am not just me, I'm not alone in anything that I do. Two also happens to be my favorite number. First, I tried some latin "Duo Audio", but that's the name of a company, I think. Flipped the words around but still wasn't fond of it. I then tried "Two Listen", the english version of the aforementioned - registered several email accounts to reserve the name, and here we are. A name that is (or at least will be) partially my own real name - and that also reminds me every time I kill someone or make a post, that there is more than just one Listen - there are two of us.
Yes, I am obsessed. And crazy as hell. Neat, huh?
Edit: As a side note, I also created a Listen logo for the both of us - I needed one with which to sign my artwork (I'm an artist). I created the one you see in my avatar and signature. It symbolizes our favorite letter, contains our name, and the design near the top resembles the design of the engagement ring I gave to her.
