Headnod

The involuntary and repetitive head reflex one exercises when listening to a really tight jam (song). The individual bobs his/her head to the beat of the jam, exuding a feeling of confidence and coolness that quickly vanishes once the jam ends.

Once "Nothin' But A G Thing" came on the speakers, Maleeq's headnod intensified dramatically and the hos noticed his good vibe.

This beat is so headnodic that I was nodding the whole time without even realizing it.
