The Destination--Call Sign?

I was just thinking back on Christmas...traveling to Central Washington (once my least favorite place I'd ever been--now I slightly enjoy it) when the caravan decided if we were to properly engage in walkie-talkie conversation we would need call signs, our given names just would not work. So the names emerged...from where I still cannot put my finger on. My identity became "maverick" and I find it mildly fascinating. It came to my attention that the names cannot be changed, yet I see no need for them to be. In the span of 39 long seconds it seems we have properly call-signed everyone in fam fairly accurate!
