A position in an MMF threesome branching off of the standard missionary position such that the first man is on the
bottom, the girl straddles him and lays on his stomach and the other gentleman enters her from behind. The two gentlemen make up the buns of this 'hamburger' while the fine lady in question is the
meat. This can work as both a standard DP or as a DV or DA, though the latter two are certainly only recommended if the
meat has said experience.
