pack-a-snack
A situation where you're stuck waiting and you're just going to deal with it because you're too lazy to do anything else.
Waiting for my lunch in the cafeteria was a pack-a-snack moment. I just sat there and took it.
I waited in line for my turn at the DMV and it was like a pack-a-snack from the pits of hell.
I sat in my car for 30 minutes in traffic and it was the ultimate pack-a-snack.
