When you are excited to get high on some good marijuana but you are either interrupted during smoking or don't bake an edible for long enough... And get only a little bit high kind of like getting dome from a chick only to have your parents walk in before you can finish. Green balls leads to temporary insanity and or feening for some more dank.
Yo man I was just sparking up my first bowl of the day when I was punched in the face by a member of the LBGT community I felt the initial effects of the bowl but got green balls when I couldn't finish it because of said gay/lesbian/bisexual/transexual being.
