Any tips & tricks when growing grass?

When we moved out here, all this was where the house it was just a big yard of dirt. I went to the local Ace Hardware and bought a 125 pound sack of bermuda grass. Just chunked it out and it was up in three days. ........but when it sprouted, it was RED. I mean blood red. Took it two weeks to get green. That was in July 2002. I aint watered it. I ain't fertilized it. I ain't weeded it. I've driven over it, dug it up, pissed on it and it just keeps gettin thicker every year.
