Sudden bonor syndrome (SBS) is a very serious condition that has to be releived within a very short space of time with serious sexual exercise. Often if not releived in the critical time SBS causes the penis to become so erect that the veins seize up and the penis drops right off. Then the flat spot that is formed turns to a vagina.
male: shit i havnt had sex in some time, my penis feels tight like its going to drop off
female: i think you have SBS, come with me quickly.
