For those who have remained blissfully off of Twitter, a site that remains uncomfortably popular with sociopaths and morons like me, the “ratio” is when a tweet is so bad that the number of retweets and favourites it accrues becomes greatly outnumbered by hostile replies. It is one of the few beautiful things about the site, a poisonous rose growing on polluted soil, or at least an injoke that hasn’t been completely run into the ground yet.
