Platonic facesitting
A dynamic physical activity involving two people, definitionally neither sexual nor romantic in nature, characterized by the uke adopting a superior position relative to the other participant, who, depending on circumstances, is described by theorists as the nage, tori, or shite. Lingual stimulation is neither necessary nor sufficient for an act to constitute platonic facesitting, but it has been observed with increasing frequency in the decades since the publication of the Henry Miller's "The Smile at the Foot of the Ladder", considered by Australian art critics to be the seminal text in the study of the phenomena. See for criticism the works of the Jakarta Nihilists, who argue, with shocking abruptness, that platonic facesitting is neither possible nor desirable.
I saw Sally and John engaged in platonic facesitting at the beach last Thursday. John used to talk about standing up for women's liberation, now he approaches the project from a different posture.
