what does asdfghjkl mean?

[Fin]

As the people below said, it's just someone dragging their finger across the middle line of a keyboard. asdfghjkl is typically used to express a mixture or overload of emotions, and usually has the same effect as "I can't even," or other expressions of something or someone being too cute, too funny, or too scary, or possibly even frustration with this too cute, too funny, or too scary object/person.
