Did you know that film crews have their own walkie talkie lingo?
10-1 (10-100): Standard washroom break. Although this falls under more than just walkie etiquette and is more a common set etiquette. “10-1” or “10-100” simply means your going to the bathroom.
What’s your 20: This means “where are you?” Often times asked before given a task.
Flying in: This tells others that you are flying in to set or bringing something in.
