(as in Right to Work STATE) A state that does not require you to become a member of an acting union to get an acting job. For example, Texas, Florida, Tennessee are 'right to work' states. New York and California are not. This one can be very confusing, but don't worry about it. When you're ready to join a union, your agent will guide you!
What you may hear the camera person yell--that means the camera is rolling.
Pay attention. This means something is happening!
SAG: 
Screen Actor's Guild. Go there or see AFTRA.
(as in AGENT) This means the agent has agreed to abide by the rules and regulations of the unions. These agents are the good guys. There are non-franchised agents who are also the good guys, but it's a lot harder to tell which ones they are. Actor Beware.
See minimum.
The Screen Extra's Guild. A Union for Extras. Don't look for this union in a right to work state. Their big territory is Hollywood!
(as in 'report to the set' or 'he's on set') The camera location and the area around it--where all the activity seems to be on a shoot. Tread carefully in this area. This is where you sign in with the assistant director--make friends, he/she will be a director some day (or maybe you will)!
Sound effects abbreviation. They are usually done in a sound studio. Sometimes on the set, you'll hear someone yell "bang" or "crash," you'll have to react as if you've heard them. Pay attention. Listen. It's your job!
Only those pages of a script on which your character has lines or action. Tough to do an audition with just a few lines, but that's usually the way it is. Sometimes, you can read the whole script in your agent's office the day before the audition. It's always good to ask your agent.
By the way, this term is mostly used in the THEATRE. Asking for your "sides" in a film audition could result in several different things happening. 1. They could be impressed, "gee, this one's got theatre training!" or 2. "Gee, another theatre snob!" Your choice. Your audition! Just be aware!
"The Shoot" is the job...whether a commercial shoot or film shoot or if you're a model, a photo shoot.
"I've got a shoot tomorrow" is correct.
"I've got to shoot tomorrow" is correct if you're operating the camera.
"Shoot" or "Oh, shoot" is appropriate only if you've just hit your thumb with the hammer...or you didn't get the part.
and if you happen to hear, "You're in my shot!" then it would be quite appropriate to say, 'shoot!'...(but only under your breath!)
At an audition, if they say "slate your name and agency", look into the camera, say your name and agent with as much of your real personality as you can--without being too obnoxious! Slate is also the 'clapper' they use in film to make a 'mark' which allows them to synchronize the sound and the picture together in editing.
What the sound man/mixer yells to let the director know his tape is up to speed and he's ready for 'action'. If you hear "SPEED", you better know what to do next...otherwise "take one" will turn into "take two" which could turn into "bring me another actor!"
What you hear on set when they are almost ready to start. Take a deep breath and get ready--ACTION is not far away.
No, you don't want to be a stand in. At least not as a career. You get to stand there while the star sits in their trailer. You stand while they focus the lights, you stand while they focus the camera, you stand while they practice the camera moves and you stand while they stand there looking at you. That's what you get paid for. Of course, you might get a big break just standing there--but don't aspire to be a standin unless you really like standing!
