An adjective describing an unpleasant person, place, or thing. Often associated with an undetermined precursor as to why this person place or thing is so unpleasant.
A burst of noise (a.k.a. "static") heard after a FM radio transmission ends. The random static sound is actually the radio trying to decipher the ambient background noise into meaningful audio. Usually this noise is hidden from the listener with the squelch function on the radio. In typical squelch systems, the audio circuit is turned off if the radio isn't receiving a signal of a certain minimum signal strength. The squelch tail occurs when the transmission has just ended and the radio circuitry doesn't respond quite fast enough. This is remedied by systems like STE or Squelch Tail Elimination by Motorola which send a brief subaudible tone right before the end of the transmission so that the audio circuit turns off before the modulated signal ends. Creative use of CTCSS like turning off the tone generation circuit on a repeater before the repeater tail will work for radios using tone squelch on both transmit and receive.
The Squelch-Meter is the only accurate way to measure a woman's pussy squelch. The meter goes from 1-10. Pussies with a squelch of 1 have dry ass, Sahara desert pussies. Pussies with a squelch of 10 have wet, drippy, Niagara Falls pussies. A 10 is the best score, but pussies with a squelch of 6 and up are acceptable. The squelch is more important than any other rating a woman can receive.
