Rainbow moshers basically love the things that regular moshers love.
Friends, alcohol, being original, having fun and rock music :)
Rainbow moshers will wear jeans and hoodies like moshers but often wear bright colours as well. Rainbow moshers love clothes that actually have pictures of rainbows on or are fluorescent accompanied by black hoodies and jeans.
Obviously rainbow moshers are still moshers so conflict with chavs is still at large.
