Acid

An acid (from the Latin acidus/acēre meaning sour) is a chemical substance whose aqueous solutions are characterized by a sour taste, the ability to turn blue litmus red, and the ability to react with bases and certain metals (like calcium) to form salts. An aqueous solution of an acid has a pH of less than 7 and is colloquially also referred to as 'acid' (as in 'dissolved in acid'), while the strict definition refers only to the solute. An acid usually contains a hydrogen atom bonded to a chemical structure that is still energetically favorable after loss of H⁺ (a positive hydrogen ion or proton). A lower pH means a higher acidity, and thus a higher concentration of positive hydrogen ions in the solution. Chemicals or substances having the property of an acid are said to be acidic.

There are three common definitions for acids: the Arrhenius definition, the Brønsted-Lowry definition, and the Lewis definition. The Arrhenius definition defines acids as substances which increase the concentration of hydrogen ions (H⁺), or more accurately, hydronium ions (H₃O⁺), when dissolved in water. The Brønsted-Lowry definition is an expansion to include solvents other than water: an acid is a substance which can act as a proton donor. By this definition, any compound which can be deprotonated can be considered an acid. Examples include alcohols and amines which contain O-H or N-H fragments. A Lewis acid is a substance that can accept a pair of electrons to form a covalent bond. Examples of Lewis acids include all metal cations, and electron-deficient molecules such as boron trifluoride and aluminium trichloride.

Freak

In current usage, the word "freak" is commonly used to refer to a person with something strikingly unusual about their appearance or behaviour. This usage dates from the so-called freak scene of the 1960s and 1970s.

An older usage refers to the physically deformed, or having extraordinary diseases and conditions, such as sideshow performers. This has fallen into disuse, except as a pejorative, and (among the performers of such shows) as jargon. "Freaks" of this kind can be classified into two groups: natural freaks and made freaks. A natural freak would usually refer to a genetic abnormality, while a made freak is a once normal person who experienced or initiated an alteration at some point in life (such as receiving surgical implants).

"Freak" continues to be used to describe genetic mutations in plants and animals, i.e. "freaks of nature." "Freak" can also be used in a verb form, and can mean: "to become stressed and upset". Usually, in this form, the word is followed by "out" to complete the phrase, "freaking out". However, this meaning and usage is usually considered slang. Adjectival forms include "freakish" as well as "freaky." The verb "freaking" (or, "freaking out") means "engaging in panicked or uncontrolled behavior"—for example, as the result of psychedelic drug use. "Freaking" may also be a minced oath used in place of "fucking," e.g. "Oh my freaking God!" The word is a homophone of "phreak" (referring to the illegal hacking of telephone systems), which it probably inspired.

Terror Night

Terror Night is a 1987 slasher film directed by Nick Marino. It was released on DVD in the United States as Bloody Movie.

Critical reception

Allmovie called it a "substandard horror film" and that "the real fun to be had in Terror Night is its virtually limitless source of bizarre trivia for dedicated exploitation buffs."
