You've probably seen friends and colleagues sharing small animated images on Twitter and Facebook.
A bit like this one in fact. They can be a great way to make your point, or just have a bit of fun. It's now really easy to find these, by using Giphy which is a search engine for searching animated gifs. In early October Giphy passed 100 million daily users who send 1 billion gifs per day and viewers watch more than 2 million hours of gifs per day.
To be honest, the search engine isn't that great - you're pretty much stuck with single word searching, so don't expect anything elaborate. There are a few basic categories that you can browse through, but it's not brilliant. Giphy does have some extra tools that you can use however to create your own animated gifs on your smartphone or tablet device, and you can upload them onto the site to share with other people.
In summary, a poor search engine in terms of functionality, but great for finding funny and amusing images.
