BSG: Bed Spread Gas
An ancient fossil fuel that appears to originate from a near-infinite domestic source.

BSG is most commonly encountered when approaching a bed partner and disturbing the BSG reservoir surrounding the partner, with reservoir retention integrity breached via a change in bed spread conformation (I.e. sheets and blankets got moved).

A release of BSG can be responded to with ’what the frack is that’ or ‘you rotten baby’, with correct reply being ‘welcome to flavour country’.

BSG is the primary energy source powering blanket-based Dutch ovens.
