According to grindhousedatabase.com: In layman’s terms Pinky Violence means "sexed up, bad girl action films" by the Toei studios.
Often referred to as the ultimate book on the subject; J-Taro Sugisaku and Takeshi Uechi’s ’Pinky Violence – Toei’s Bad Girl Films’. Generally the genre is also considered to include Teruo Ishii’s Tokugawa/Torture epics from the late 60’s, which put the genre on the world map.
Pinky Violence flourished for the next 10 years and came to its end in the late 70’s.

"Teen friends Tummler (Nick Sutton) and Solomon (Jacob Reynolds) navigate the ruins of a tiny, tornado-ravaged town in Ohio that is populated by the deformed, disturbed and perverted. When not gunning down stray cats for a few bucks, the boys pass their time getting stoned on household inhalants. Elsewhere, the mute Bunny Boy (Jacob Sewell) dons rabbit ears and is bullied by kids half his age, and sisters Dot (Chloe Sevigny) and Helen (Carisa Glucksman) dodge a pedophile." Rotten Tomatoes
