Combination of "blunder" and "number crunching," describing the exasperating experience of trying to figure out which supermarket item is giving you more for your money on a dollar per ounce basis.

A lot of times these days supermarkets will break down the cost per ounce right on the face of the shelf price tag. However, sometimes you find yourself blundering through basic algebra, trying your best to hold your own. Forget about it if you're trying to convert between grams and ounces: you're just done, and you'll make your decision on some other factor.

If you have your phone with you, you can use the calculator function to avoid blunder crunching. In no case, however, must you mumble to yourself out loud as you try to do the calculations.
Don't be the guy mumbling to himself while trying to decide between Starkist tuna or the store brand. Keep your blunder crunching as private as possible.
