What else does ratio mean?

On the social media platform Twitter, a ratio, or getting ratioed, is when replies to a tweet vastly outnumber likes or retweets. This means people are objecting to the tweet and considering its content bad.

Where does ratio come from?

You might remember from math class that a ratio is a proportional relationship between two numbers. For example, if I have two carrots for every one apple, my carrot-to-apple ratio is 2:1, or 2/1 as a fraction.

In the Twittersphere, a ratio specifically refers to the number of replies to a tweet versus the number of likes and retweets. The importance of this ratio was first called out by user @85mf, who noted on March 7, 2017 that U.S. congressman Jason Chaffetz had a tweet with 701 replies and only 23 retweets and 108 likes. @85mf commented: “Nothing on this site makes me happier than reply-to-RT ratios like this. That is the ratio of someone who fuuuuu***d up.”

In April 2017, an article in Esquire, “How to Know If You’ve Sent a Horrible Tweet: A Deep Dive into The Ratio,” gave a longer description of this phenomenon. Essentially, showing you like something on Twitter is easy: You simply like or retweet the comment. It takes more effort, however, to leave a negative comment, so, if lots of people do so, then it must be a sign the tweet has really stepped in it. By fall 2017, the noun ratio had been verbed, as in I’ve been ratioed or Let’s ratio this guy.

Before Twitter analytics became a thing, having something that was well-ratioed, like ingredients on a sandwich, meant it was well-proportioned. But since 2017, there is little positive about being ratioed. It means your tweet has been taken down by the hive mind.

How is ratio used in real life?

Ratios are obviously found all over math and science and their uncountable real-world applications, where it’s just another way of expressing the proportional relationship between two numbers.

But on social media, a ratio refers specifically to this relationship between comments, retweets, and likes, and it implies a post is objectionable.

While it started on Twitter and is most commonly found there, users’ posts can be ratioed on nearly any social media platform, including Reddit and Instagram.

The definition has also expanded to refer to the ratio of the number of people a user follows based on how many people follow them—a sign of internet popularity as well (or lack thereof).

Getting ratioed on Twitter has become such a trend that it’s spawned its own hashtag, #ratioed, which salty tweeters use to note particularly unpopular tweets.

In the gaming world, your ratio more likely refers to your k/d ratio—your kill-to-death ratio, meaning how many players you’ve killed versus how many times you’ve been killed.

More examples of ratio:

“It’s widely considered that if you have a ratio of 2:1 for replies to retweets, you’ve done something wrong. So if your ratio gets higher than that, you know you’re in trouble.”
—Rachel Hosie, The Independent (UK), April 2017
