half-smile

A smile, but only one side of your lips curl up. It is used seductively by both guys and girls to look attractive.

From across the room, he gave me a half-smile and winked.

The Michael Half-Smile

Smiling while trying not to smile, then doing it anyways, but not really.

Guy 1- Did you see that guy do the Michael Half-Smile?
Guy 2- yeah man. He looked really confused.
