It has multiple defintitions,
Killed, for instance, but also can
mean that you're totally f*** up on acid.
To shout "GET TOASTED!" at someone, for instance, means that you think that person should eat acid and
kill their egos.
GET TOASTED!! (Eat acid and
die!)
Sorry I'm not
going out tonight, I'm totally toasted in my room right now, petting my fish.
I can't drive right now I'm way too TOASTED man. I'm
TOAST!
