Randometer
A concept or device which measures the 'randomness' of a given event, object, behaviour, situation or being. It can be demonstrated using the lower arm placed horizontally with the hand of the other arm supporting the elbow of the 'randometer' arm. The randometer then moves from horizontal up to a potential 180 degrees to indicate the 'randomness' level required. It can also fluctuate as required during the randometer measuring process.
Use the Randometer when a dwarf unicycles past on a pink unicycle wearing pink wellington boots smoking a large pipe and humming the theme tune to Mighty Mouse.

radiometer
A radiometer or roentgenometer is a device for measuring the radiant flux (power) of electromagnetic radiation. Generally, a radiometer is an infrared radiation detector or an ultraviolet detector.1 Microwave radiometers operate in the microwave wavelengths.
While the term radiometer can refer to any device that measures electromagnetic radiation (e.g. light), the term is often used to refer specifically to a Crookes radiometer ("light-mill"), a device invented in 1873 in which a rotor (having vanes which are dark on one side, and light on the other) in a partial vacuum spins when exposed to light. A common belief (one originally held even by Crookes) is that the momentum of the absorbed light on the black faces makes the radiometer operate. If this were true, however, the radiometer would spin away from the non-black faces, since the photons bouncing off those faces impart more momentum than the photons absorbed on the black faces. Photons do exert radiation pressure on the faces, but those forces are dwarfed by other effects. The currently accepted explanation depends on having just the right degree of vacuum, and relates to the transfer of heat rather than the direct effect of photons. 23
A Nichols radiometer demonstrates photon pressure. It is much more sensitive than the Crookes radiometer and it operates in a complete vacuum, whereas operation of the Crookes radiometer requires an imperfect vacuum.

radiometric dating
The scientific process of measuring the decay of elemental isotopes such as Carbon-14 to determine the age of organic or non-organic matter.

Blexas
Texas is categorized as a swing state in presidential elections, but has voted for Republicans more times than for Democrats in recent history. As such, as demographics change political alignments, some Democrats believe that Texas will vote blue, or Democratic, due to their Hispanic and African American voters, who often align themselves with the Democratic Party's liberal wing.
Blexas has been cited as possible in the upcoming decades, but only if Democrats continue to win the Hispanic vote in bigger margins.

Ratfucker
Brought to public attention by Bob Woodward and Carl Bernstein in the book on the fall of Richard Nixon, All The President’s Men, ratfucker was Nixon’s term for a political operative who sows chaos among opponents; an agent provocateur. It is thought to have originated among campus political rivalries at USC, and seems to have some usage in the US military.
Along with Nixon’s other ratfuckers, Roger Stone caused fights at otherwise peaceful Democratic Party protests to generate a false narrative that the Democrats were violent and dangerous.

countrypolitan
Term used to describe someone who is a mix of both rural (country) and urban (metropolitan) lifestyles/upbringings. He/she is typically equally comfortable in both settings and is able to seamlessly slip back and forth between the two, appreciating the characteristics of each.
That ol' gal of mine drives the 12 lane freeway during the week and a John Deere on the weekends. She likes opra and the Grand Ol' Opry. I love them countrypolitan women.
