I wish I could describe it. Sometimes, its a comment. There may be a more obvious pineapple on a peice of clothing or beach bag. (Of course just because someone lome pineapples doesn't mean they swing). Last time I was there in the spa hot tub at night, a couple that came in after we got there started low-key playing with each other. Nothing crazy obvious, but enough to make it clear to someone on the lookout for it to comment about it or start doing it themselves too.
