blundershirt

When the sleeves of an undershirt bulge out from the bottom of the sleeves of the shirt worn on top. See teespurt.

Also, a shirt that is crappy for any multitude of reasons: ugly, ill-fitting, poorly-made, smelly.
Just realized my favorite concert tee shirt becomes a blundershirt as soon as I put any other shirt over it.

Dressed in a hurry and didn't notice I was sporting a teespurt until lunch. Spent half the day looking like a dweeb.
