What is the definition of Postal Seeds?

"Postal seeds" are like the unsung heroes of the mail world – they're small packets of potential, tiny packages of possibility that float through the air, waiting to be planted and sprout into a new, unexpected delivery. Imagine if you were the postal worker of the universe, but instead of delivering letters, you only delivered seeds. That's basically what postal seeds are – they're tiny plant life forms waiting to take root and grow into a new tree of mail delivery, but with a whole lot of unexpectedness involved.

Here's an edgy example sentence using "postal seeds": "The postal worker's latest 'eed' – a rare species of dandelion – was mistakenly sent to the moon, causing an intergalactic plant invasion and the subsequent cancellation of all future 'wildflower' delivery services."
