An unsuspected attack on one's testicals. By swiftly, but forcefully "tapping" the testicals, the victim will then proceed to fall to the ground and roll around in extream agony(if the "tap" was strong enough the pain will travel up to the stomach) whilst shouting obscenities. Afterwards the victim will find a way the get back at the attackers, thus starting a jimmy tapping war.
Bert got jimmy tapped by bob then 20 minutes later he jimmy taped bob with a literature book in retern.
