Didn't Austin actually refuse to play along when he came back that one week last year? I have a vague memory of laughing as Tess asked him to get his "guns" out one last time and he flatly refused. Gavin did look acutely uncomfortable, though. Poor guy! I imagine he'll bear the brunt of that this year, unless Tess decides to go for the new male pros as well as the contestants.
I have to admit, I'd never heard the word before Tess either. I remember being distinctly confused (and a little worried!) the first time she addressed Austin that way.
