Pineapple has picked up a surprisingly specific swinger-community code (a pineapple displayed upside-down on a porch, or worn on clothing) signaling openness to swinging lifestyles — a meme that spread widely enough that the emoji itself sometimes gets flagged in that context, alongside its everyday use for tropical vacations and piña coladas. It joined Unicode in 2010 and is drawn with fairly uniform spiky-leaf styling across vendors.
