so my wife thought it would be nice/fun to kill weeds with round up, we had A LOT of dandelions and she sprayed the crap out of them, well, they are dead but since round up is non selective it killed my grass too. there are now about 20-30 6' yellow circles all over the place and at least a couple on my neighbors side (our lawns meet). what are my options in fixing this, my research shows the grass is toast and wont come back, is this true? do i need to basically get rid of those circle patches and reseed?

Great.
plant in fall, in the meantime, laugh about it- unfortunately she didn't spray the whole lawn. You still got to mow the remaining.
My wife has something about even one blade of crab grass. She eventually she sprayed the whole lawn with Roundup. Fifth year bare dirt. Now she is on the mission to kill moss.
YdirtMV.

What kind of grass do you have? What region are you in? I'm dealing with a similar issue, but on a smaller scale and intentional.
I just got tired of weeds coming back in my Bermuda, so I put Round Up on the worst spots. Waited a week, tilled the soil to loosen it up some, then dropped a seed, starter fertilizer, and a top dressing of compost, and now I'm watering regularly while I wait for the seed to take.
It all depends on how much rain you get as to when you can remedy your problem. I believe Roundup recommends waiting at least three days before you reseed. I would water those spots good for at least the three days if it is not raining. It probably would be better to wait one week to make sure you don't waste the seed. One of the harder problems might be matching the new seed with the specific kind of grass you have? You don't want green spots that don't match the rest of the lawn. I guess you could try some of that quick start seed in fertilizer; if you can match up your grass.
Maybe somebody can tell me if this is one wacky idea? If you are talking about 6 inch brown circles and you don't have to worry about burning the neighborhood down; would it be worth it to try to burn off these small brown circles with a blow torch? Maybe it would do more harm than good? I am just trying to think of a way to get rid of the brown for new green grass.
Problem solved next time with this. Just use the right amount once a year and you'll see the difference and not worry about killing the grass.
