A sexual act between two lesbians. One lesbian, typically the dominant one in the relationship, proceeds to defecate on the vagina of the other lesbian. The two then proceed to scissor, smearing the fecal matter over both of their vaginas. Oftentimes the two lesbians will not shave their pubic hair for a few weeks prior, building up a bush to place the "mulch" around.
