Freak
(重定向自Freakish)
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).
