Of course, there's been more uses to squeezing than just signaling the "all clear" to the referees or their opponent. Indeed, squeezing has also been used as a warning, like the famous WrestleMania 22 street fight between Shawn Michaels and Vince McMahon. During the match's most famous spot, when Michaels hit McMahon with an Elbow Drop off a ladder, the referee squeeze McMahon's in order to prepare him for the spot. While this would seem to be weird at first glance, it was less so here, given McMahon couldn't see Michaels on account of the trashcan that was put over his head.

But perhaps the most famous example of squeezing in wrestling came during a match that many consider to be among the greatest in the history of wrestling; Bret Hart vs. "British Bulldog" Davey Boy Smith at SummerSlam 1992. The match has gone onto become famous for Smith's hometown victory, it's well paced back and forth action over the course of a half an hour, and because of the recent revelation that Hart essentially willed the match into greatness by calling it the whole way, after Smith admitted to him early in the match he had forgotten all his spots.

So where did the squeezing come in? Right before the finish, when Smith infamously sat down on a Hart rollup attempt to score the 1-2-3, and the Intercontinental Championship. In order to set up that spot, Smith had to reverse an Irish Whip by Hart, sending him to the ropes. It was then that Hart squeezed Smith's wrist, reminding him of the reversal. As such, the Hart-Smith match is a reminder of how important squeezing is, whether used to keep someone safe, or to remind a wrestler of what to do next.
