i'm decreased - a dumb way to say you're dead like you're not even trying to

a dumb way to say you're dead like you're not even trying to be fancy or cool about it

I'm decreased, bro. I died in my sleep and I didn't even get to finish my cereal.

I'm decreased, my dog ate my homework and my mom found out.

I'm decreased, I failed math and now I'm stuck in 6th grade forever.
