A slang term for "coprophilia, fecophilia, fecalphilia or coprolagnia". It is a paraphilia
involving sexual pleasure through human feces, or rather to its excretion. In the case of consuming feces, generally scat play is safe when played alone and safe with a partner if one uses protection so as not to come in direct contact with a partner's excrement.
