A [ Bolthead] is a person who tends to be a bit of a chav, but Bolthead was coined long before chav was in common use.I first heard the term ''Bolthead'' in 1979, in Kingston upon Thames, UK, in these circumstances- i was short of my busfare, and so was my friend, and he said, ''don't worry, put yer best Bolthead voice on, and ask for a child ticket'' [we were teens]- he said boltheads were rough or ''common'' types, that have little culture, the sort one now sees on programmes such as ''Jeremy Kyle''
