A contractor or mechanic who makes up, or exaggerates problems in order to upsell you on additional, or more expensive services.
The last HVAC guy who came in was a total ghostbuster. He was saying that my brand new furnace needed to be replaced, and he even wrote up a quote to replace the entire house's ductwork. All the furnace needed was a new igniter part. So I hired someone else who replaced the part for a fair rate.

Ghostbusting refers to the act of searching the floor for possible pieces of drugs that may have been dropped while they were being consumed. Typically seen with users of crack cocaine but sometimes powder cocaine, which is a white substance. They are looking for something that is almost never there.
