Here's a breakdown of the phrase:
"He did": Indicates that the person took action or completed something.
"His big one": Refers to a noteworthy or outstanding accomplishment.

In summary, "he did his big one" is a way of highlighting someone's remarkable achievement or success in a particular endeavor.
