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.

usually happens to americans traveling abroad, especially in latin america and africa. basically means that you have to go and cant.
Oh shit--my intestines feel like they're not only tied in a knot, but a double knot with a bow and that someone kicked them--this SBS is killing me!
