A Gussak is a primitive tool often used on airplanes. It is not good for much, and can often be found lying around in offices. When used, does not produce great results.
Dude, can you pass me the Gussak, I think I found a use for it.
When one is gusak'd they have intoxicated themselves heavily, although one must have ingested a multitude of differentdrugs simultaneously. Being gusak'd means that you are so high that you do not know what is going on around you.
Yo bro! Im so so Gusak'd right now that I dont know where the fuck I am.
