a type of dance generally linked to metalheads and goths. People are generally found doing this at metal/rock concerts. It consists of shaking the head violently in an upwards and downwards motion so that your hair flys around and goes in everyones mouth around you. People normally end up with a headache after doing this.
The state at which one is trying to stay awake but failing resulting in the slowly down-turning head and quick rise up when one realizes their falling which occurs over and over resulting in a motion that when sped up resembles the act of head-banging.
Introduced by a popular sports commercial in which the culprit was recorded on their phone falling asleep and then the video was sped up and put to slayer sounding music.
The rock 'n roll head banging motion made by a baby/small child while trying to fall asleep in a seated position. The baby/small child's head slowly nods down only to be jerked back up from the uncomfortable position, creating the head banging motion.
Expressing a feeling of being ecstatic. When your neck is cutting itself off ,your ears and burning and shredding themselves inside your temple for love of a skull, your eyes are getting eaten from the inside out, your eyelids are involuntarily fluttering, your hands are shaking, your legs are broken, you have no toe nails, your love of the world at that exact moment. Please never stop. Please.
