What does fluffer mean?

A "fluffer" is typically a term used in the adult film industry to describe a person whose job is to help performers maintain arousal between scenes, often by providing physical stimulation or encouragement. The term can also be used more broadly to refer to someone who enhances or boosts the atmosphere or mood in various contexts. In a non-adult context, it might imply a person who enhances or embellishes something, often in a superficial or exaggerated way.
