2. Any person thats hair is in a swirl (like a tornado), and looks like they just received a swirly, whether the hair is dry or wet. It is also specifically used for people living in areas with lots of tornadoes, mostly redneck areas of the South and Midwest (excluding the North Coast). Places with Swirly Head Ass people are: KC, St. Louis, Indianapolis, Oklahoma City, Des Moines, Omaha, Cincinnati, and every other place in tornado alley which just happens to be filled with 95% rednecks and hillbillys.
Dude 2: "I gave her a Swirly Head Ass last night, I guess that bitch doesnt shower"
