Singapore Sling (1990)

Michele Valley and Meredyth Herold are mother-daughter slaughterers who go balls out for the gross out in Singapore Sling (1990), a demented Greek horror that's a total whore for gore. The two madwomen live together in a big abode, whiling away their days with family activities like taboo sex, sadomasochism, fruit-aided masturbation, and murder re-enactments. And they're not the types to sit on life's sidelines and let other people get their hands dirty, oh no: Michele and Meredyth make their own material! This gruesome twosome re-enacts murders that they themselves committed, for another popular pastime at their ancestral booby house is hiring servants and then serving them up to eternity. In gooey, grody pieces. When a private detective named Singapore Sling (Panos Thanassoulis) shows up inquiring about a woman named Laura whom he's obsessed with (and who is, of course, no more-a), mom and daughter take him prisoner and torture him in trashy, titillating, and truly terrible ways.
