Or is it Crab Grass? Spell it either way. Give it a space in the name — no big deal. Give it a space in your lawn? Trouble! Allow it in the smallest part of your yard or garden, and it takes root and takes over.
The weed is called by many names in different parts of the country, sometimes referring to the actual weed, Digitaria Sanginalis or Digitaria ischaemum.
But the label people use often is applied to any number of different varieties of weeds. Some of these names are: devil grass, quack grass, bermuda grass, goose grass, barnyard grass, and you may know a few more.
The varieties, hairy or smooth, also make it more difficult to be sure the one you are looking at is the same as what different experts are describing (like your brother-in-law across the country).
More significantly, the appearance of this master of disguises varies incredibly depending on the maturity of the weed, the growing conditions, the competition, and the availability of nutrients or water, plus a tendency to be just plain ornery!

Those balmy locations happen to be very conducive to weed growth and everything else. So they probably rely greatly on these weed killers for crabgrass control, right? Nope. Make that a capital NO!
