< Andys> oh dear
  < Andys> in ruby, symbols are represented with a prepended colon
  < Andys> eg.   :flag
  < Andys> so some guy tshirt that said ":sex"
  < Andys> which everyone at railscamp knew meant "Sex symbol"
  < Andys> he wore it until someone pointed out that to non-rubyists it said "Colon sex"
