In is down, down is front. Out is up, up is back. Off is out, on is in. And of course, left is right and right is left. A drop shouldn’t and a ‘block and fall’ does neither. A prop doesn’t and a cove has no water. Tripping is OK. A running crew rarely gets anywhere . A purchase line buys you nothing. A trap will not catch anything. A gridiron has nothing to do with football. Strike is work (in fact, a lot of work). And a green room, thank God, usually isn’t.
Now that you’re fully versed in theatrical terms, break a leg. But not really.
