A
mood or
aura that someone "radiates" while doing something. Typically, this
mood is laid-back and nonchalant, though the energy type can vary. Another word for this would be vibes.
1) "Dang, that
girl just brought a 2-litre bottle of soda to
school, and now she's just hangin in the back of class with her earbuds in. I wish I could channel that energy."
2) "
Bro, I just hung out with the theatre kids, and I swear, they radiate this energy that nobody else can."
