The same method that cause water in a drain to swirl. A star is a gravity well, like a hole, where particles fall into. A randomly variable number of particles are hitting each side -- the side that gets more particles sets the spin in motion, which in turn gives influence to the rest of the particles falling in, accelerating spin.
