campaign to replace bōsōzoku-related terms with less cool-sounding alternatives

As part of the campaign to replace bōsōzoku-related terms, the police encouraged people to call them 'chinsōdan' instead.
A compound of 珍 (chin, 'rare' or 'strange') + 呼 (ko, 'call' or 'name') + 運動 (undō, 'movement' or 'campaign'). The term was coined to describe a specific social campaign, likely originating from media or police initiatives.
