Sometimes referred to as RBS, Random Boner Syndrome is a severe medical condition plaguing men around the world. As implied, a young male will, unexpectedly get and erection boner often at an inappropriate time. It is completely random, with no visual or mental stimulation required to cause it. Most males will not experience this very often after puberty.
