The term 'Pea Piercer' is a job title for someone who uses a TINE, which is a four-letter metal prong, to pierce peas. This job is typically done in a factory setting and involves piercing the peas so that they can be cooked or frozen. The TINE is used to puncture the pea's skin, allowing the pea to be cooked or frozen without losing its shape or texture. Pea Piercers must be precise and accurate in their work, as any mistakes could result in the peas being damaged or unusable.
