permacoked
A state of inebriation caused by excess consumption of C17H21NO4 (cocaine for laymen), resulting in self-generation of the aforementioned substance inside the nasal cavity, removing both the need for the act of purchasing and the act of snorting this substance due to permanent presence of an everlasting self-reinforcing high.
Luc is clearly permacoked... Ever since that night he pushed JP off his bike decades ago, he's just been riding that high without ever coming down.
