she/he was partial to her/his humans being pre-boned!!

Get the pre-boned mug.
V. When one has sexual relations with someone of interest before even arriving at a party.
Party Goer 1: Dude, Nelson's such a champ.
Party Goer 2: How so?
Party Goer 1: He pre-gamed by chugging a four loco. Then when his girl came down from the shower; they pre-boned right there. They left for the party after all that.
Party Goer 2: Damn, nice work.
