Resonance Cascade 

A fictional phenomenom where waves of energy combine in a continual loop (cascading). In essence, the energy multiplies out of control. See Resonance Reversal.
I never thought I'd see a Resonance Cascade, let alone create one!

Nuclear magnetic resonance spectroscopy (NMR) 

Nuclear magnetic resonance spectroscopy, most commonly known as NMR spectroscopy or magnetic resonance spectroscopy (MRS), is a spectroscopic technique to observe local magnetic fields around atomic nuclei. The sample is placed in a magnetic field and the NMR signal is produced by excitation of the nuclei sample with radio waves into nuclear magnetic resonance, which is detected with sensitive radio receivers. The intramolecular magnetic field around an atom in a molecule changes the resonance frequency, thus giving access to details of the electronic structure of a molecule and its individual functional groups. As the fields are unique or highly characteristic to individual compounds, in modern organic chemistry practice, NMR spectroscopy is the definitive method to identify monomolecular organic compounds.
Person 1: Do you think our laboratory needs an NMR-spectrometer?

Person 2: I've heard they're unbelievably expensive, but Nuclear magnetic resonance spectroscopy (NMR) is an essential analytical procedure for sure .

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.

The number of years you are still sexually active
While our lifespan is the number of years we will live, our healthspan is the number of healthy years we will have and our sexspan is is the number of years we will continue to be healthy enough to continue having an active sex life.

Word of the Day on October 28, 2026
A lighthearted reaction upon receiving disappointing news of some sort. Usually something that isn't a particularly a big deal, esp. when it primarily affects someone else - sort of a mild schadenfreude. Sometimes doubled or tripled, and possibly said in a sing-songy voice for added comedic effect to imitate a muted trumpet, which is how the meme originated.

Surf Dracula Syndrome 

A phenomenon in film/television series, most notably streaming series, where the main premise is drawn out to such a point that it takes an entire season or more to get the parts of the series the audience is actually interested in seeing.

For example, if a series is titled "Surf Dracula," a majority of viewers would tune in expecting to see Dracula surfing by the first or second episode. However, the entire first season would instead be tedious padding and backstory before finally ending with Dracula surfing in the last five minutes of the season finale.
I watched "Smallville" on Netflix the other day. Dude, it was ten seasons of filler before he finally flew! Major Surf Dracula Syndrome!
