Pack of blow
A pack of blow is something you pretend is important, and you either suck it or blow it, and you act like it’s the best thing ever.
I got a pack of blow and it was just a tomato. I blew it and it exploded.
My friend’s pack of blow was just a toy. I sucked it and it broke.
That pack of blow was just a pencil. I blew it and it flew into my mouth.
