shopping cart gridlock 

When you are grocery shopping during the rush hour and you can't get through the aisle because there are too many carts in the way, can't back up either because other shoppers piled in behind you and nobody can move.

I can't get to the tostada chips & jalapeno cheese dip, I'm stuck in shopping cart gridlock...
