British Gas Pedal
Military term used to describe the act of taking an IV bag and hooking it up to a tube. That tube is then inserted into the service members anus and then pressure is exerted on the IV bag with a foot forcing contents into the small intestine where it is quickly absorbed. Used to hydrate a service member in dire need.
Did you hear smith get a British gas pedal?

Yeah maybe that retard will start hydrating from now on.
