My nick is a catalan word..."xerraire" means talkative. I lived in Catalunya, Spain for a year.
I came up with that nick for a chat group I entered, it was sure it was going to be unique, and I was in a hurry to think up one. The name stuck...its on my domain, www.xerraire.com
I've put it on my t-shirts...
its a part of me now for years.
Its pronounced not like you would think. The "X" makes a "sh" sound. Phonetically, I suppose you could pronounce it, SHUH-RYE-RUH
Catalan is a very beautiful language.
And that is how I took my nickname.
