Definition
A "grease monkey" is an informal and sometimes derogatory term for an auto-mechanic. It refers to someone who works on cars and gets covered in grease and oil. It's not always the most respectful way to describe them. It implies a focus on the dirty, manual labor involved in car repair. While some mechanics might use the term jokingly, it's best to use 'auto-mechanic' or 'car-mechanic'. π
