The pineapple represents hospitality and welcoming. A pineapple is placed on a porch or mail box by swingers to signify that a swinger party is going on. A pineapple is turned upside down when a person is in search of a swinger party. Originally it was turned up side down in the individuals shopping cart. But pineapple popularity has made it accepts on clothes and other items. Swingers use this symbol to identify each other in public.
My neighbor left an upside down pineapple on my porch last night. I think he wants to swing.

The act in which a male, during 69, ejaculates on his partner's face and then immediately flips her off of his body. He must then immediately grab a handful of glitter (which he had in his hand, pocket, or on the bedside table) and "cast" it into his partner's face. The glitter will adhere to the partner's face, leaving her "under his spell". The male can then, if desired, yell "EXCALIBUR!" at the top of his lungs.
"So how was it with Gabi last night?"

"Oh man, she had no idea, I pulled off the Upside-down Merlin. That bitch is totally under my spell."
