“What frozen alcoholic beverage should you drink if you need to poop?”/“A Piña Colonic.”

“Piña colonic” (piña colada + colonic) is a jocular drink name. “Piña colonic,” a mistake for “piña colada,” was mentioned in the Cheech & Chong comedy film Nice Dreams (1981). American comedian and actor Robin Williams joked about “piña colonics” in 1984. Homer Simpson, on the American animated sitcom The Simpsons that aired on January 31, 1999, sang about “piña colonics” to the tune of “Escape (The Piña Colada Song).”

Wikipedia: Piña colada
The piña colada (/ˌpiːnjə koʊˈlɑːdə, -nə-, -kə-/; Spanish: piña [ˈpiɲa], “pineapple,” and colada [koˈlaða], “strained”) is a sweet cocktail made with rum, coconut cream or coconut milk, and pineapple juice, usually served either blended or shaken with ice. It may be garnished with either a pineapple wedge, maraschino cherry, or both. The piña colada has been the national drink of Puerto Rico since 1978.
             
Wikipedia: Colon cleansing
Colon cleansing (also known as colon therapy) encompasses a number of alternative medical therapies claimed to remove nonspecific toxins from the colon and intestinal tract by removing any accumulations of feces. Colon cleansing may be branded colon hydrotherapy, a colonic or colonic irrigation. During the 2000s internet marketing and infomercials of oral supplements supposedly for colon cleansing increased.
       
15 June 1981, The Arizona Daily Star (Tucson, AZ), “‘Nice Dreams’ another ‘reefer-madness’ spinoff” by Jacqi Tully, pg. C3, col. 4:
Sit on a beach and drink “piña colonics,” for one.
 
16 April 1984, The Daily Dispatch (Moline, IL), “Robin Williams an ‘original’” by Michael Blowen (Knight News Wire), pg. 20, col. 1:
DURING a recent 90-minute interview at the executive offices of Columbia Pictures, Williams would impersonate a drag queen, mimic the late George Jessel as Polonius, create a Marin County, Calif., housewife going for “Pina colonics” and toss in a dozen accents for good measure.

Seeking to distinguish himself in this genre is Dr. Ron Schwartz, an Atlanta gynecologist who spent $20,000 this week to fly three cohorts to Los Angeles and rent a room at the Loews to promote “Smooth Operator.” This personally produced sex farce is big on busty nurses, bathroom humor (a patient will be given a “pina colonic”) and broad racial stereotypes.

Not *colitis*.  Homer got a coupon for a free *colonic* - which is an enema. (And if you don’t know what that is, I’m not about to go into it.) The joke was that he was singing “The Pina Colada Song”, as in the coconut drink…and….well, you get the rest of it.

“Good, good, although that . . . What was that drink last night? A pina colonic? It sure was rich.”
 
“Pina colada, Andy,” I laughed.

Pina Colonic
A term used by Homer Simpson during the episode ‘Sunday, Cruddy, Sunday’. It’s an obvious reference to the 1979 song ‘Escape’ by Rupert Holmes (also known as the pina colada song)

I invented a new beverage just in time for the weekend.  A cleanse and a cocktail all in one.  It’s the new piña colonic!  #wellness
