people with nipi boi fetish are plagued by recurring and sexual thoughts, fears, or images (obsessions) of the great man that they cannot control. The anxiety (nervousness) produced by these thoughts leads to an urgent need to perform certain rituals or routines (always sexual). The compulsive rituals are performed in an attempt to prevent the obsessive thoughts or make them go away.
