You can find this filter through
Filters->Noise->Slur.
Slurring produces an effect resembling melting the image downwards; if a
pixel is to be slurred, there is an 80% chance that it is replaced by
the value of a pixel directly above it; otherwise, one of the two pixels
to the left or right of the one above is used. All or only some pixels
in an active layer or selection are affected, the percentage of affected
pixels is determined by the Randomization (%)
option.

Random Seed
Random Seed controls randomness of slurring.
If the same random seed in the same situation is used, the filter
produces exactly the same results. A different random seed
produces different results. Random seed can be entered manually
or generated randomly by pressing New Seed
button.
When the Randomize option is checked, random
seed cannot be entered manually, but is randomly generated each
time the filter is run. If it is not checked, the filter remembers
the last random seed used.
Randomization (%)
The Randomization slider represents the
percentage of pixels of the active layer or selection which will
be slurred. The higher value, the more pixels are slurred, but
because of the way the filter works, its effect is most noticeable
if this slider is set to a medium value, somewhere around 50.
Experiment with it and try for yourself!
Repeat
The Repeat slider represents the number
of times the filter will be applied. Higher values result in
more slurring, moving the color over a longer distance.
