A person getting double trouble at once, like getting spanked by two teachers at the same time.
I was a D-sandwich when my mom yelled at me from the front and my dad threw a shoe from behind.
At the mall, I got ambushed by two friends, one on each side, and it was a D-sandwich from hell.
In the middle of a fight, I was a D-sandwich because my brother tackled me from behind while my friend hit me from the front.
