MELISSA BLOCK, HOST:
Time for some more trade lingo. We've asked you to send us phrases or bits of slang from your world - insider terms of the trade that would stump people on the outside. And today we have this phrase.
MICHELLE HACKMAN: Toi, toi, toi.
BLOCK: Toi, toi, toi - spelled T O I. That was sent to us by listener Michelle Hackman of Cary, Illinois. She's a professional opera singer and she told us she heard toi, toi, toi for the first time when she was in college. She was backstage before a performance.
HACKMAN: A voice teacher said it to one of the performers. And I said what is that? I've never heard that before in my life. It basically means break a leg. That's the term we use instead of break a leg or instead of good luck.
BLOCK: And when you heard it and you asked about it, what did they tell you?
HACKMAN: They said it was just the way to say good luck. And there was also a spitting motion. I'll pretend to spit over the shoulder. It's to ward off evil spells or bad luck. It's also - comes from the German term for devil, which is Teufel. And so they say it could be a shortened version of that. So speaking the devil's name to ward him off.
BLOCK: So I'm trying to picture this. If you're saying this, Michelle, you're - every time you say toi, are you turning to one shoulder or the other and sort of kind of making a spitting motion?
HACKMAN: Well, there are people who take it really seriously and do the toi, toi, toi and then pretend to spit over their shoulder. And then typically though you just say it - toi, toi, toi.
BLOCK: Michelle Hackman, thanks so much for talking to us.
HACKMAN: Thank you.
BLOCK: And do you have any interest in singing us out with something?
HACKMAN: (Singing) I am Rosina - dainty mouth.
BLOCK: Great - which is from what?
HACKMAN: That's from a performance I just did of "Hansel and Gretel" with Main Street Opera. And I played the witch. And we did it in English, not German.
BLOCK: Well, keep going.
HACKMAN: (Singing) I dearly love all boys and girls. I'm innocent as a newborn child. That's why the children come visit my house.
BLOCK: That's great. I didn't have time to tell you toi, toi, toi before you started. But you didn't need it. You did great.
HACKMAN: Oh, we said it enough. I think we're covered.
BLOCK: OK, great. Michelle, thank you so much.
HACKMAN: Thank you.
