What is Semiboned?
1.
One of those annoying partial erections. Not quite hard enough to masturbate with, but hard enough to be seen by people if you stand up. They're also rather difficult to get rid of, because by the time you get one you want to get the rest of the erection.
Jason: brb getting milk -gets up-
Mom: You're semiboned, son. I don't need to see that.
Jason: -.-
