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)

'If you like pina colonics and getting caught in the rain, passing out in the ocean.'

Pina Colonic 

A Pina Colonic is a sexual expedition in which a man first ejaculates into his partners asshole, then pops a straw and drinks from it. Best enjoyed with coconut shavings and a wedge of fresh pineapple.

(term obviously derived from combining pina colada and colonic.)

"Man, that Pina Colonic was just what I was craving"
