My name is StreGatta (I'm Italian)
This are the union of Strega and Gatta (witch and cat)
and I chose it because in the game everyone says I am a witch and that I scratch with comments (and not only)
StregattO is also the name of the Cheshire cat in the Italian adaptation of Disney's Alice in Wonderland. The name has been used occasionally in literature to refer to a witched (or witching) cat.
As for mine... well, if you're not Tuscan isn't really straightforward... for the Tuscans, supercazzola brematurata come fosse antani, anche per due.
For everyone else, it spawns out of some sort of gibberish or gobbledygook way of speaking to confuse the interlocutor in a comedic way that was used occasionally in the Divine Commedy by Dante and rehashed by Mario Monicelli in the dark comedy Amici Miei (My Friends).
Growing up in Florence we would throw nonsensical words at each at other trying to catch each other guard and, if the other missed that it was a nonsensical word and would reply asking what was said, we'd say "Puppa!", literally "suck it", sort of gotcha.
One of those nonsensical words was Stubaski.
