Gizphixiation 

A condition where penis is forced into the throat of another impeding the normal action of breathing. The remaining space betwix phallus and larynx is taken up with cum, causing choking and ultimately death. Not recommended.

''The rim of me cock slipped passed the gap of 'er wisdom teeth as I cummed officer. I think she's dead''

''Its ok son. That's no crime its Gizphixiation.''
