noun
Colloquial use for getting into the swing of things, high spirits, or a lively atmosphere. Often written in katakana as ノリ. Possibly derived from 気乗り.

He's always in good spirits and livens up the party.
この曲はノリがいいから、つい踊りたくなる。
This song has a great rhythm, so I can't help wanting to dance.
気乗り specifically means 'inclination' or 'willingness to do something', while ノリ in sense 4 is broader, covering mood, energy, and rhythm.
Derived from the verb 乗る (のる, 'to ride'). The 'mood/energy' sense may be an extension from 'getting on board' with a situation, possibly influenced by 気乗り.
