killjoy

商業主義に走った日本式バレンタインデーのあり方に異議を唱えるひとも多いようです。ここのkilljoyは文字通りの意味になるのかもしれませんが、Greenさん、確認をしてください。（Astroriver）

Killjoys demand end to Valentine's Day

As Japan celebrated Valentine’s Day on Saturday, a group of killjoys marched through Tokyo protesting what it called the “passion-based capitalism” of the annual celebration of romance.
Members of Kakuhido, which translates as the Revolutionary Alliance of Men that Women find Unattractive and claims on its website that “public smooching is terrorism”, walked through the busy Shibuya district waving banners with slogans demanding an end to Valentine’s Day.
