hoka-hoka
Lesbian sex among bonobos (one of the two primates that humans evolved from). Scientific name "genito-genital." More specifically, one female bonobo wrapping her arms and legs around another and clinging, facing each other and pressing their vulvas and clitorises together, rubbing them sideways in a rapid rhythm. Done for sexual pleasure.
Loretta and another female bonobo did the hoka-hoka and had big grins on their faces and squealed loudly.
