Unless you’ve read Shakespeare’s plays, you probably haven’t seen the word “sirrah” before. It’s obsolete now, but it used to be a derogatory way of referring to somebody. Something like “Bring us some drinks, sirrah, and make it snappy.” Not that I could ever look down on anyone who brings me drinks.
Plucking an insulting word off the linguistic scrap heap and making it my own just felt right to me. I hope to be your sirrah, now and always.
