Pink Flamingos (1972)

In director John Waters' ultimate, exploitational trashy/cult film ("An Exercise in Poor Taste") with homage to the Manson family, and multiple examples of grotesque sexual acts and behavior - the first in a bad taste-laden "Trash Trilogy" followed by Female Trouble (1974) and Desperate Living (1977):

• the many oddball characters living in a Maryland trailer (with plastic pink flamingos) of overweight transvestite trailer park matron-diva Divine/Babs Johnson (drag queen Divine or Harris Glenn Milstead) including her delinquent son Crackers (Danny Mills), her traveling companion Cotton (Mary Vivian Pearce), and her half-dressed, mentally-ill corpulent mother Edie (Edith Massey) who sat in a playpen and ate hard-boiled eggs
• tabloids had named 'Babs Johnson'/Divine as "the Filthiest Person Alive"; one early example was her public urination

Edie (Edith Massey)	(l to r): Edie and Babs Johnson (Divine)
Babs (Divine)	"The Filthiest Person Alive!"

• the continuing conflict between Babs (and her family) and the envious and rival couple ("two jealous perverts"): transgender blue-haired Raymond Marble (David Lochary) and red-haired Connie Marble (Mink Stole) who were involved in black-market criminal activity with their manservant Channing (Channing Wilroy); girls would be kidnapped by chloroforming them, locking them up in a basement, artificially inseminating them by injecting Channing's sperm into their vaginas through a dispenser tube syringe, and then waiting nine months to sell their babies (in their "adoption clinic") to lesbian couples
• the exhibitionism scene of a clown-masked, tall Raymond exposing himself to two females lunching in a wooded park, after tying and attaching a very long kielbasa sausage to the end of his penis, and then stealing a left-behind purse
• the shocking scene of rape-sex between Crackers and the Marbles' spy Cookie (Cookie Mueller), as voyeuristic Cotton looked on from a nearby trailer window, and two live chickens were crushed between them during bestiality copulation
• Babs' over-the-top birthday party scene, with a cake decorated with the words: "Happy Birthday Babs The Filthiest Person Alive", featuring bizarre sex acts, including a topless woman (with pasties) dancing with a snake around her neck, and a gay male contortionist (anonymous, uncredited as the "Singing Asshole") who ascended onto a performance stage, laid down on his back with his legs in the air, and musically sang or 'lip-synched' to the tune of The Trashmen's "Surfing Bird (Bird is the Word)" ("Mau-mau-mau") by flexing his anal sphincter!)

Babs' Birthday Party	Stripper	The Singing Asshole at Babs' Birthday Party

• disgusted by the party as they spied upon it, the Marbles summoned the police - followed by the killing and cannibalistic eating (simulated) of a quartet of policemen (reminiscient of Night of the Living Dead (1968)) after being axed into pieces
• the scene of the surprise revelation of a Trans-sexual's (Elizabeth Coffey, credited as "Chick with a Dick") breasts and male genitals in an outdoor park to thief Raymond, when he selected his next victim and 'she' flashed her penis at him
• the outrageous scene of mother-son incestual sex (fellatio) between Babs and Crackers, after they vandalized the Marbles' home and licked all the furniture
• the revelation that Channing, after being castrated by one of the freed pregnant women in the basement ("I'm gonna cut that big fat worm right off you") (off-screen), had bled to death (Connie Marble: "He's been castrated. His penis is gone!")
• the scene of Babs' vengeful kidnapping and trial (kangaroo court) of the Marbles for burning down the trailer, and for "first-degree stupidity" and "assholism"; Babs delivered a stunning "filth politics" speech to TV and tabloid reporters, including Mr. John Vader who asked if blood was a turn-on: "It (blood) does more than turn me on, Mr. Vader. It makes me come. And more than the sight of it, I love the taste of it. The taste of hot, freshly killed blood...Kill everyone now! Condone first degree murder! Advocate cannibalism! Eat s--t! Filth are my politics! Filth is my life!"
• the bound-and-gagged couple were tied to a tree, coated in tar and feathers, and gunned down one-by-one in the head by Babs/Divine in front of the press - it was a 'live homicide'

• the scatological, disgusting gross-out scene of Divine/Babs eating real fresh, recently defecated dog feces in a competition to become the 'World's Filthiest Person' at the film's conclusion - she gagged and then smiled at the camera in a close-up - finally succeeding in attaining the title
