lets just say,if mum had said infront of some police she had just bought her daughter a box full of disco biscuits they woud not react to it kindly.
she had no clue what disco biscuit is well known for and neither did dad which is why had got up the dictionary definition [as seen in photo below].
dad said it is named as such because of the smarties looking like lights,they are actualy very nice and can recommend them though unfortunately there isnt one bit of MDMA in them.
