When you line up three shots of alcohol and take them immediately following one another. There must be one shot of vodka, one shot of rum, and one shot of whiskey for this group of shots to appropriately be called "the devil's third nut". The shots serve as a metaphor for Lucifer's three testicles.
Friday night was the worst... I started off with the Devil's Third Nut at nine o'clock and I was already trashed.
