Moon Kiss 

It is a slight but soft kiss that someone gives you on the corner of your lips.

My friend think he's so smooth that I didn't notice he gave me a moon kiss after he kissed my cheeks.

It was unpleasant to moon kiss after eating spicy Mexican food.
I asked him if he wanted to moon kiss. He said no because it would hurt his hemorrhoid.

half moon kiss 

When your girlfriend (or boyfriend if you swing that way) stops mid way through giving you a blowjob to kiss you on the lips.

A full moon kiss would be when they kiss you on the lips, after they have given the blowjob.

The former is arguably preferable.

Guy 1: "Dude, Alice is so good at giving head. She even stopped half way through and gave me a half moon kiss!"

Guy 2: "Nice!"
