Venusian nerve pinch
From Tardis Wiki, the free Doctor Who reference
The Venusian nerve pinch was a manoeuvre used by Venusians. It was applied to a pressure point at the shoulder, which would nearly instantly render the target unconscious and induce short-term amnesia. The Seventh Doctor used a Venusian nerve pinch on a guard while helping Anthony Rupert Hemmings escape from Britischer Freikorps HQ. (PROSE: Timewyrm: Exodus)
