Either crab grass or what my mom called quick grass (I think). I had some success with Ortho brush killer but you have to remember it'll kill the grass too. If it's taken over a whole area, try splitting a black garbage bag and spreading it over the area for a few days (weigh down edges). Let the lack of sun and extra heat cook it. Then rake a bit and seed w/grass you want. It'll probably show up again though since it's runners are prolific...
