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.

Short for ultimate bias. Typically used by fangirls and fanboys to describe their favourite celebrity amongst the many that they are fans of.
