The awkward and uncontrollable pubescent condition of genital arousal at the most inconvenient or inappropriate moments.

This does occur in post-pubescent males, and is still referred to as 'Teenage Boner'.
1) When you are sitting on a bus and you get a boner for no reason (or because there is a good looking girl staring at you) and you have to get off the bus at the next stop, but because of your raging hard-on you have wait for a few stops for the teenage boner to go down.

2) You get a teenage boner in class just before dismissal.
