Jing Wing
It is an unwanted half-boner. It isn't at the point of a full erection and isn't completely limp. You are on the fence and you are not sure which side of the fence you are going to land on. It may become a full erection or your penis may just fall back into dismay. You may get one from waking up in the morning, or the act of a chick possibly grinding on you.
