an erection that comes for no reason. it just happens. you could be in the locker room with a bunch of dudes. dont worry if it happens there. as long as it only happens once youre probably not gay, just unlucky.
its a quiet day in penisville. some young sperm cells have crawled into the penis and are playing in the veins.
Cell 1: Hey, whats that sound?
Cell 2: surprise boner!
Cell 1: The blood wasnt supposed to come till we see the hot chick on the bus!
Cell 3: DIVE!
