My Flashcards

Definition

Meaning

A person who habitually uses LSD, a psychedelic drug.

A hippie or countercultural figure stereotypically associated with the use of hallucinogenic drugs, particularly during the 1960s and 1970s. Can sometimes be used more broadly for someone fascinated by psychedelic experiences.

Linguistics

Semantic Notes

The term is heavily tied to the counterculture of the 1960s/70s. It is a compound of 'acid' (slang for LSD) and 'head' (slang for an enthusiast or habitual user, e.g., 'pothead'). While descriptive, it can carry a mildly pejorative or stereotyping connotation. It is largely historical.

Connotations

Common Pitfalls

Translation Traps (for Russian speakers)

  • Не переводите дословно как "кислотная голова" — это будет бессмысленно. Это сленговое обозначение человека.
  • Не путайте с химическим термином. Здесь 'acid' — это ЛСД.
  • Слово 'head' здесь не означает 'глава' или 'руководитель', а 'пользователь'.

Common Mistakes

  • Using it to refer to any drug user (it's specifically LSD).
  • Using it in modern contexts; it sounds antiquated.
  • Spelling as 'acidhead' (sometimes written as one word).
