On any given day, there are roughly 40,000 tweets with the goat emoji, according to Twitter data reviewed by The Wall Street Journal. There were 333,665 tweets with the goat emoji the day after Mr. Brady’s last Super Bowl win. The uptick of goat emojis amounted to a nearly 750% increase.

The history of the goat emoji is shorter and stranger. The etymology dates back to 2010 when it was introduced to the lexicon with other livestock emojis. An update to Apple’s operating system in December 2016 included a goat makeover. What was a white Saanen goat is now a brown Toggenburg goat with a bushier tail.

Another version of the goat emoji underwent its own round of cosmetic surgery last year with an update to Google’s Android operating system. “Our goat is no longer so angry,” said Jennifer Daniel, the company’s emoji designer, who drew the goat herself.
