The rating of a couple in their ability to take on a third wheel
during a date. Normally ranked on a scale of 1 to 10, 10 being totally able to include the third wheel
with utmost comfortability and non-awkwardness, and 1 being an inability to do so and therefore making the third wheel feel awkward
Last time I was with Fred and Sally, they went at it and totally ignored me, I give them a -1 from a scale of 1 to 10 on the wheel worthiness scale.
Sue and Steve are chill. Their a fun couple. I give them a solid 10, totally wheel worthy
