Origination from the verb "oscilate", Osk pronounced "Ahsk". It is A word used to describe the intense feeling one undergoes when coming up after smoking large quantities of Cannabis, rolled in a blunt per se. This feeling may emerge in a variety of ways, but most commonly, osking reveals itself in either paranoia, extreme realizations, and in the general feeling that ones' own world is spinning. osk may also refer to a "One Shot Kill" strain of marijuana that will guarantee an gratifying oscilation.
Hearing that face melting guitar solo combined with the feeling of me hitting this blunt sure is making me osk right now!
