@chai2,
No idea.
For the longiest while I thought it was tsartsarpan sort of rhymed with marzipan. After a time I found out he was an ice cream fanatic and knew more about ice cream than a politician knows about corruption and lies. It was later that I realized I could enlarge the font on the computer and then learned his actual screen name.
There is though the unanswered question= Why did he really leave Massachusetts and find a pad in New York? I want the real story, not some trite fictional account. As I wait, perhaps he can tell me who the genius was that developed licorice ice cream.
As to his evol beginnings, that's best kept quiet I am sure.
