Maybe it’s eye catching? Maybe it’s an unique name that no one else will have? Maybe it was an accident?? Maybe it’s rememberable? Maybe I simply just can’t spell?
Without giving any too many details, it’s an old inside term.
Will I ever fully explain the meaning? Probably not. I wouldn’t want to give away something that’s special to me and the person I share it with! It just makes work just a little more fun and maybe a little more personal. Everytime.
