A fork of Rural Dictionary
When a female is performing fellatio and begins to either orally stimulate the anus, or insert her fingers into the anus. In this situation the male pushes back on the female with one outstretched arm on her head and a bent leg on her shoulder. The resulting position resembles the Heisman trophy.
Dude! She was sucking my dick and then she started to like my asshole and wanted to finger me too so I totally started heismaning
