look up any word, like bukkake:
 
1.
1. A sexual act. You get head from a bitch, then before you cum, turn her head around and put it in the toilet and flush it for a swirly then you jam your dick in her ass, turn her around again and skeet all over her hair, and let it dry. It is complicated and takes many tries to master. If done correctly, the following day the bitchs hair will be sticking up like a damn Super Saiyan, a white-haired super saiyan at that.

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 1: "Hey dude whats wrong with ur girlfriends hair today? it was all white and crusty and stuck up like a Super Saiyan Goku?"
Dude 2: "I gave her a Swirly Head Ass last night, I guess that bitch doesnt shower"
