The report was based on 2017 data from Tenor's GIF-sharing platform, which handles more than 9 billion searches per month.
The researchers excluded GIFs that are perennially popular (e.g., "happy birthday").
A "yay" GIF featuring actor Jonah Hill was the third most shared of 2017.
A GIF of athlete/broadcaster Shaq laughing was fourth, and an "oh yeah" GIF of former US president Obama was fifth.

The researchers found that searches for GIFs that conveyed a nervous emotion increased around the US presidential inauguration.
