Nebraskan handshake
An otherwise normal handshake from an incredibly brave and strong person (e.g. a member of the Coast Guard's elite secret special operations force) that in one motion pulverizes the receiver's hand and causes a chain reaction of intracerebral and subarachnoid hemorrhage leading to certain demise. Ability to give a true Nebraskan Handshake is extremely rare and studies show a significant linkage to the amount of scrod the giver consumes.
Congratulations, you just earned yourself a top spot on the list of people awaiting a Nebraskan handshake. I hope you're left handed because I'm going to grip your right hand tighter than your true love. And you get the privilege, of hearing your bones break before the power of embrace causes your veins to explode.
