The fetish of floor tiles. Originating from a 4chan thread where the op admitted to getting sexually aroused by tile patterns and saving pictures with different patterns for masturbatory purposes.
Having a fetish for floor tiles isn't abnormal at all imo. I'm sure a lot of normal people share this fetish too.
The act of laying or sitting on the floor either alone or with friends. Often used to destress and chill out. Usually an unplanned event and is triggered by one person laying or sitting down and others joining.
"Why are all of you on the floor, there are chairs right there"
"We're having Floor Time right now."
