After a long night of drinking, if a man goes to sleep without ejaculating, his penis will not have the normal amount of erections throughout the night.

This will result in a "Boner Bonanza" the following day. A "Boner Bonanza" is an astonishing number of unintended erections during the day.

This could prove embarrassing.
Dude, I got wasted last night and did not rub one out. Looks like I have a "Boner Bonanza" today.
