I rarely play guitar, and play bass a LOT, but for whatever reason my guitars have names and my basses don't (yet, anyway).
One is a Gretsch resonator guitar that I call "cookie." I bought it years ago to take busking, and the very first day I had it, dropped it square on the pavement from the unzipped gig bag on my back (distracted by my dog + tourists when packing up). Despite a truly terrible noise it somehow suffered only a small chip when a nice Martin or something would have exploded. I've seen the thing fall face first, er, fretboard first, straight over on hard surfaces way too many times. It never skips a beat, I don't even bother checking for damage anymore. So I figure it's a tough cookie..
The other is a hollowbody electric that I call "easy" because the action is so low, thing plays itself.
