Being intoxicated on three substances simultaneously.

Generally Alcohol, Marijuana, and some other substance. The third ingredient is really personal preference but some popular choices include:

Mushrooms,
Morphine,
Cocaine,
Vicodin,
Oxy,
Nicotine,
Caffeine.

A good trifecta is the nicotine, weed, alcohol which gets you in a good party mood and balancing the three types of buzz is very important.
Dude 1: I had an amazing Tri Fade going last night. I smoked two blunts, was dipping for for like an hour and then pounded 5 beers and 6 shots.

Dude 2: Sounds nice. Tobacco focuses the senses, Alcohol makes you want to party, and weed just makes it all feel so pleasant.

Dude 1: Hell yeah, I'm trying the Quad Fade next friday!
