A "Keldabe handshake" was a euphemistic slang term for a Mandalorian unarmed combat technique that consisted of violently gripping a Humanoid opponent's groin. Debilitatingly painful for the victim, the technique was noted for its ability to neutralize a Human foe with one hand. The term derived its name from Keldabe, the capital city of the planet Mandalore, and a play on the handshake, a common gesture of greeting across the galaxy.
