Did some research on the Internet on just exactly this annoying little weed is. Come to find out it is Nutgrass or nutsedge, and it's not too easy to kill.
You can do a search on Google to find plenty of info and pictures if you think this is what you have. It grows at a amazingly fast rate and makes your yard look like it hasn't been mowed in a week 2 days after mowing it.
I am currently trying this Bayer Advanced Lawn Weed and
Crabgrass Killer. Never been a fan of putting chemicals on
the yard since I have had dogs, but this stuff is annoying.
Currently at one week since application and I do not see the nut grass brown and dried up. The crabgrass and clover has turned brown and died, but not the intended target. Although I have noticed that the nutgrass has NOT sprouted right back up for days after a mowing. The instructions say to apply a second application 2 weeks after the first, so I'll see what happens.
