A type of transcendental yoga-like meditation. When sticking your arms straight out into a T position can cause the feeling of oneness with your surroundings. Can cause a feeling of contacting angels or being abducted by aliens. Myth surrounds this pose in antiquity.
Dude I was listening to Trance music on top of this mountain in a Jesus Pose getting into a state of trance. Unreal Bro
If you aren't going to the Concert of the Year because you're too broke, agoraphobic, or datelesss, you can always meta-pose, i.e. sneer & say, "that scene was a lot more happenin' before the posers got to it."
