What is an email bounce? (basic definition)

An email bounce occurs when a message cannot be delivered to the recipient and is returned to the sender with an error code.

Soft bounces are temporary issues such as a full inbox, while hard bounces are permanent, for example when an address does not exist.

It is like a ship returning undelivered cargo to its sender because the destination port was closed or missing.
