As a guy is receiving fellatio, the person providing it ducks out of the way when he ejaculates.
Damn girl! That's a lucky duck.

It rhymes.

The most basic meaning is someone or something with dumb luck.
My dog's name is Lucky Duck because he's lucky I got him out of the pound and he isn't a duck.

A lucky duck was crossing the road and didn't get hit by a car somehow. Asshole.
