When you are so fucked up words like clapped, geeked, or fucked, wouldn't do justice to the situation.

when you're hungover as shit after a spending a night drunk as a skunk

when you’re high asf and other words are not doing it justice. a mix of shmacked and geeked
can also be used in verb form to replace the word smoke so u can be discreet: “are u tryna shmeek later?”
