What is probie meaning?

"Probie" is a slang term that is commonly used in the fire department to refer to a new or inexperienced firefighter. It is derived from the word "probationary" or "probie," which is the official title given to a firefighter during their initial period of employment. Probies are typically subjected to a rigorous training program, which includes a mix of classroom instruction, physical conditioning, and on-the-job training. They work under close supervision from more experienced firefighters and are required to demonstrate their skills and knowledge before being granted full-fledged firefighter status.
