Low scat is basically scat but with not actual shit/feces, like personality excrement/jelly shit. Simple as.

Fabrizio romanoff comment was true, low means the presence of those are way minimal, like the way describe describe low lolicon +90 has the same meaning

@Fabrizio Romanoff wtf man

That is not what the tag means. Low scat means it contains scat but said scat does not pass the prescience rule, i.e, isn't a significant part of the work.

If you are looking for it you already know what it is
