Big One

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.

"Did you see how he planned that romantic date with the candles and music? He really did his big one there!"

This means he put a lot of effort into making the date special and it turned out really impressive.
