IDK if we have already done this thread before, but what does your username mean? 

My initials are D. and J. and for some reason, I heard meister somewhere, hence DMeisterJ

I got it a long time ago when I was really young, I guess i thought I was cool + my favorite number = cool48, it never changed since then.

I have no clue, care to enlighten?

Clearly you didn't note the sarcasm in my post. :)

And Rol has a naked mole rat named rufus as his pet.

There are twelvethousanad members on this site, that means I should have twelve thousand posts.

Tommy Westerman = twesterm

My old undergrad used your first initial and up to the first six letters of your last name for your email address (assuming it wasn't already taken) so we have twesterm.

Oh, to tell the story of Montana: The Two Axes would be too arduous a task, even for a great and powerful moderator.

Wii

 That's exactly how I got mine except it was the first initial plus seven.
