I SHUMMM??!
When you’re so hungry or so impressed by something you see that you yell it like it’s the end of the world.
I SHUMMM??! I haven’t eaten in three days and this burger looks like it’s from heaven.
I SHUMMM??! That guy just jumped off a cliff into a pool. Why?!
I SHUMMM??! My homie brought out a whole cake. I’m gonna die of happiness.
