Coward's Ratio 

When a status (especially on Twitter) has significantly more likes than it does retweets/reposts/shares. Usually happens when people like or agree with a statement, but are afraid to share on their own profile for fear of being mocked or embarrassed. Usually involves taboo sexual remarks or embarrassing bodily functions.

If someone writes about how all of us have had a crush on a hot cousin at one point or another, and 9.4k people have liked it but only 37 people have retweeted it, that's the Coward's Ratio.
