My vote is “Jizz”, because it’s phonetic. Which will eventually become JizzScript, infuriating everyone bothered by ATM machines and PIN numbers.

I think that name will bother people for more reasons than that XD

But that was of course your point.

Just say the letters? Jay Ess in english, Jota Ese in spanish, etc…

What other way is there ?

In poland people will not be sure if it's Jot Es or if they want to sound cool and say Dżej Es so it's nice and english. Big problem!

You pronounce it as "javascript" in casual conversation, disregarding Oracle's trademark because they're not going to do shit about it. Not even Oracle. Xerox can't stop people from trampling all over their trademark in casual conversation and neither can Oracle.
