radio

There are many different types of radio receiving circuits:
-Crystal (see above)
-Regenerative
-Tuned Radio Frequency (TRF)
-Superheterodyne

Modern radios are superheterodyne. The superheterodyne circuit replaced the TRF and regenerative circuits by the 1930's, and crystal sets were nearly dead until solid state radio emerged.

.22

A common caliber of rim-fire weapons. This is often thought to be an ineffective caliber by people who cannot hit what they are aiming at. Used properly, it can be extremely fatal, especially with high-velocity ammunition.

The burglar died from a single shot to the head from a .22 pistol.

crock

Short for "crock of bullshit."

True beauty is on the inside? What a crock!

Comment submitted with Request to Delete: "It is hard to understand "crock" by giving a saying "crock of bullshit"; it's like defining basketball as "what they use in a basketball game"

belch

Often used as a synonym for burp. A belch, however, is an obscenely loud, thunderous, and often foul-smelling burp.

A belch rang out signaling that the fat man had finished his meal.
