Where does your user name come from?

This is my first post here so hopefully ya'll won't judge me for youthful indiscretions. Arch is my last name and arch23dmt was my original AOL user name. The 23-dmt refers to a certain fast-acting psychedelic which while extremely intense, wears off after about thirty minutes. It is still my username for every website I sign in to. I was in high school and decided to be "cheeky" but since nobody ever knew what it meant I just kept it.

No points for guessing mine....

My last name "Robinson" spelled backwards is "Nosnibor"...which sounded vaguely Russian to me. First name is John, and John, in Russian, is "Ivan".

It’s a title of nobility on my home planet.

Lmr? Interesting.
