remove implication peeing_self -> peeing
Really, this implication pisses me off.
I don't think there is a good enough reason for peeing self to signify an ongoing urination action. Whoever searches for this tag is actually interested in the visible immediate results, such as the appearance of flowing urine along the legs, drenched or stained clothes, or embarrassed facial expressions, but not the process itself.
Instead, the implication either puts peeing on posts where the urination had already stopped, or, worse, makes some good "peeing self aftermath" posts undertagged and unsearchable - as tagging them with peeing_self would technically be wrong.
To add, I think the tag also deserves a rename, but can't think of a better name myself.
