freak out



  • noun
    (written as freak-out)
    a bout or scene of wild abandon, self-expression or loss of control. Originally, in hippy terminology, it was the result of ingesting hallucinogenic drugs, but later came to refer to any simulation of their effects.
  • verb to lose one’s self-control, to behave in an outrageous, frantic way. The phrase first described the alarming effect of hallucinogenic drugs such as LSD on some users, but was soon extended to any wild behaviour (whether viewed positively or negatively) such as ecstatic dancing. The expression originated in the USA among the first hippies and quickly spread to other English-speaking areas; it was sounding dated by the mid-1970s.
