Up-Down Ratio 

The ratio of thumbs up to thumbs down (or likes to dislikes) that everyone subconsciously calculates when glancing over items on this website or other websites with rated material to see if reading said item is even worth it.

"An up-down ratio of about 3.5, I'll definitely have to read this one!"
