Gifs often appear in Buzzfeed posts. They help you make each item in, for example, a listical, stand as an individual element which can be enjoyed and shared as a unit.
They are often used to make a potentially dull subject lively: politics for example (see above).
There are loads already available that you can either grab links to, or embed. You can also make your own.
How to find or create Gifs for your Buzzfeed post
