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!
