Who uses asdf?

Asdf can stand on its own as a keysmash, but it’s more popular to use it several times. A related keysmash is asdfghjkl, which consists of all the letters on the middle keyboard row. This is another common sequence used to express the same meaning.

ASDF as an acronym is quite common, standing for, among other things, Association of Synchronous Data Formats and Air Self Defense Force. These should not be confused for the filler/keysmash meaning of asdf. One helpful way of differentiating is that, while acronyms are capitalized, the key sequence asdf is only capitalized as a means to express high emotion.

As a common filler text in online culture, asdf in part inspired the name of asdfmovie, a popular internet cartoon.
