Name for an act in a menage a toi, or Gangsta Party (aka GP), or in layman's terms, a "3 some" with specifically two males and one female, where the female will use her hands on both males genitalia simultaneously, until both males ejaculate onto her chest.
As seen on the progressive commercial, where Flo gestures with her hands and screams "Office Party!" after the two males from a different insurance company are caught buying with Progressive.
