Built near to a gas holder, the constant smell of town gas in the air gave rise to the name used for Bristol Rovers fans of "The Gas" or "Gasheads". The nickname "The Gas" began as a derogatory nickname used by Bristol City fans, however Rovers fans now refer to themselves as Gasheads as a badge of honour. The number 12 squad shirt has been officially allocated to "Gasheads" by the club in honour of the crowd being the 12th man.
