Two people, often two men, shake hands. One of the men grips harder than the other one, and the other guy might start wincing or showing signs of clear discomfort. The guy delivering the Crushing Handshake might grin about it, having shown off his superior strength or "manliness". This could be done to show off just that, or as a hint that the other guy doesn't like you, or wants to intimidate you—for instance, if he's a rival for a love interest. Or it could be that he Does Not Know His Own Strength
. When both parties attempt to do this, the results can be embarrassing for one or both, which can be played for laughs. Can be related to Bear Hug
