GIF stands for "Graphics Interchange Format". It's a file format used for small images, often (though not necessarily) animated ones. It has nothing to do with Twitter — GIF images are used all over the place, not just on Twitter.

Drew is incorrect about the pronunciation; the official pronunciation is "jiff" with a soft "G". This is explained by Steve Wilhite, the creator of the GIF format, in the article linked below.
