I believe the lyrics is about a black prostitute pleasing a client . I can’t remember the chorous. It was at a karaoke bar so people might have been singing it badly. I believe the lyrics go like this
Coo-Chi Coo-Chi ya ya YA ya
Something something chocolat
This is from memory, so may not be perfect, but you’ll get the idea:
Gitcha gitcha ya ya da da.–Get your ya ya, daddy. (Ya ya is Cajun slang for woman/pussy.*) Gitcha gitcha ya ya he-ah.–Get your ya ya here. Mocha chocolatta ya ya–The provider of said ya ya will be a black (mocha/chocolate) woman. From Creole Lady Marmalade.–Lady Marmalade is the provider of said ya ya. She is either the madam or the prostitute.
That was the worst Cecil column I’ve ever read. He didn’t answer the question at all, never even gave it the time of day.
What I’ve read about it in the past is: The first line of that refrain is from an incantation or spell, in whatever kind of rituals they hold in Louisiana. A variation on it wound up as the title of a Rolling Stones album - “Get Yer Ya-Yas Out.”
