For images of girls pissing on the viewer. Trained on about 20 anime images. The trigger is PissOnU, and it can sometimes distinguish between three different types of piss:
PissStream - One or two solid streams of piss.
PissSpray - Many streams of piss in all directions.
PissDrops - Individual droplets falling on the viewer, rather than streams.
Other terms it might recognise are:
Blurred Foreground - for when the nearest droplets are out of focus.
Toilet - for when the viewer is looking up through a toilet seat
