If you get creative with Twitter's advanced search engine, you can track down users talking about catfights they've been in. I do this from time to time and the results are occasionally very good.
Here's some examples of things to search, just off the top of my head. Eventually, you get more creative/specific.
"i beat her ass"
"gave her a black eye"
"punched her"
"girl i fought"
"my first fight"
Tip: In the "Advanced Search" you might want tell the search engine to ignore posts with the word "dream" in it, as this will just include many posts with ladies talking about a dream that involved a fight rather than the real thing.
