cyclotron resonance

plasma in a magnetic field is heated through the resonance effect when the vibration frequency of an oscillating electromagnetic field matches the gyro-frequency of the charged particles in the plasma. This effect is known as Ion Cyclotron Resonance Heating, and enables the generation of superheated plasma over 100 million degrees celcius of temperature.

this definition is pretty much ruining the title "urban" dictionary. but every dictionary should have something like cyclotron resonance.

tug-o-war with the Cyclops

masturbate
wank
jack off
Stroke the Salami
a date with Pam and her five friends
the five finger knuckle shuffle on the one-eyed, blue-veined, purple-headed, custard-chucking, salty yogurt slinger.

"Failing to find someone to fuck after the club, Jimmy resorted to a tug-o-war with the Cyclops."
