pack-a-snack
When waiting feels like a punishment and you're just going to accept it like a good student.
Waiting for my turn at the DMV felt like a pack-a-snack and I just dealt with it.
I sat in traffic for two hours and it was like a pack-a-snack from the teacher's worst nightmare.
Waiting for my friend to get ready was a pack-a-snack that I had to endure.
