D-Sandwich
A person caught in the crossfire, like being squished between two angry people who both want to punch you.
I was a D-sandwich at the dinner table when my sister said I was ugly and my brother said I was stupid.
In the hallway, two guys started brawling, and I got stuck in the middle, classic D-sandwich moment.
At the park, I was a D-sandwich between my mom, who was yelling, and my dad, who was throwing a stick.
