A relationship that begins when two people are the only ones still awake at a party, due to the excess amount of vodka red bulls and/or jäger bombs consumed. The combination of alcohol, caffeine, and everyone else being passed out leads to the two people hooking up.
At the new years eve party, Heather and Dave were still up talking at five am. That's how their red bull romance got started.
