Mother (Mother's Day)

Mother is the titular antagonist of the controversial 80s horror movie "Mother's Day" and was the foul, abusive and criminally insane mother of two equally degenerated sons known as Ike and Addley: who she happily aids in abusing three innocent women in all manner of horrific ways only to have the tables turned on her when the women decide to exact bloody vengeance on her and her evil clan.
