Western affectations; excessively westernized person; wannabe Westerner
Derogatory term for someone overly infatuated with Western culture, often implying superficial imitation. Can refer to the person or their behavior.
He came back from studying abroad completely westernized.
I think that wannabe Westerner's fashion is a bit over the top.
西洋崇拝 is a more formal term for Western worship or adoration, without the derogatory, personal-attack nuance of 西洋かぶれ.
かぶれ originally means a rash or skin irritation; as a suffix it indicates being overly influenced or obsessed, as in 西洋かぶれ.
Standard spelling; かぶれ is usually written in kana.
Ateji spelling using 気触れ for かぶれ; rarely used.
Compound of 西洋 (the West) and かぶれ (rash, or figuratively 'being overly influenced'). The figurative use of かぶれ comes from the idea of being 'infected' by something.
