A literal drink crafted by the poor blue collar laborers of Pittsburgh's steel industry and handed down from generation to generation to its current residence of the White Eagle, located on East Carson street at the end of the south side.

Rocket fuel is a drink so strong and served so large that it must be split with a group of friends willing to go to moon.

When people use the term "this is rocket fuel" they are referring back to this Pittsburgh nectar and comparing their current drink and its strength to the legendary mix.
Steve: "Hey man we started late, how can we get caught up fast and cheap?"
Nick: "Dude, the white eagle serves Rocket Fuel!"
Steve: "To infinity and beyond!"
