This is an ???????? lora. It understands a lot of concepts: peeing, wetting, desperation, pulling clothing down or to the side, toilet use, different poses, different angles. Also check out the SDXL version, which is much better at conceptual understanding.
Here are the relevant tags it was trained on:
Core concepts
peeing
wetting self
desperation
leaking
Pose/expression
holding crotch
standing
sitting
squatting
lying
kneeling
relief
Clothing
panties
pants
shorts
leggings
swimsuit
clothing aside
clothing down
clothing around one leg
ripped leggings
Container
toilet use
peeing in container
holding container
cup
bottle
teacup
bag
bucket
potty
Angle
from above
from below
from side
from behind
Some of these tags are "compositional". E.g. desperation is a general look of needing to ???, holding ?????? means actually holding oneself. If you want the typical "potty dance" pose you need both tags. Similarly, "peeing in container" for the overall concept, then "cup", "bucket", etc for the type of container.
Generation tips
The most common resolution bucket in the training images was 448 width x 576 height. I typically use that res, with hires fix, scale 2, using latent upscaler. This lora is bit strong; depending on the model you're using it on and your exact prompt, you may try lowering the strength to 0.9 or 0.8 for a more natural look. It works best on NAI, or models closely related to NAI.
