A box full of retards. Someone who is thoroughly an idiot. Often said with a Northeastern Boston accent: "Taarhhd Box"
"Joe just locked his keys in his car with the engine running..."
"What frickin' Tard Box"

or

"All these people suck: you're a tard box, he's a tard box, they're a tard box, tard box, tard box, tard box."
