The Vulcan Nerve Pinch, in the Star Trek universe, is a technique used mainly by Vulcans to render unconsiousness by pinching a pressure point at the victim's neck.
The technique was used in other media, such as the iCarly episode iPsycho, as well as in Sibling Rivalries. It is used three times, first in "Gonzales Vs. McReary" (when Joel Gonzales pinches Gerald "Gerry" McReary), the second time in "The Curse of the Milderbeast" (when Kate McReary pinches Jose Gonzales, Joel's younger brother), and the third time was in "Straight Outta Green Bay" (when Kate pinches Eric Chavez, the main antagonist of the comic).
On all three times in SR, the pinch was done on the victim's shoulder rather than their neck, which is an error.
