On Monday night, Donald Trump boasted that he had a winning temperament — and social media went wild.

“I think my strongest asset, maybe by far, is my temperament. I have a winning temperament. I know how to win,” Trump said.

That comment was the top social moment on Facebook and Twitter, according to the social media outlets.

But before people posted about Trump’s temperament, many had to look it up.

Facebook reported Tuesday morning that 18.6 million people created 73.8 million likes, posts, comments and shares related to the debate Monday. There were also 55 million views of debate-related Live videos on Facebook.

For comparison: There were 7.4 million people using Facebook during the first GOP primary debate in August 2015 and they generated 20 million interactions.

Four out of five people (79%) were talking about Trump on Facebook compared with one-fifth (21%) who were talking about Clinton.

Twitter announced late Monday night that the debate was the most tweeted about in history.

Trump’s winning temperament was the most tweeted moment. His comments on the controversial stop-and-frisk police practice came in second. The exchange between Hillary Clinton and Trump over their plans to defeat the Islamic State came in third.

Twitter on conversations about Trump nearly doubled those about Clinton, 62% to her 38%.

On Tuesday morning Trump pointed out that #TrumpWon was also trending on Twitter.

While many people using the hashtag clearly thought Trump won, it wasn't all pro-Trump— another reminder of the hazards of equating social media volume with social media sentiment.
