Bedtime Blunder 

When one's roommate catches one in midst of a masturbatory act during the nighttime, caused by the fallacious assumption that the roommate will not be awakened by the sounds of shaking bedposts and heavy breathing.

Dude!... my roommate made a bedtime blunder yesterday and woke me up!

bedtime blunders 

Getting caught masturbating while your roommate because of one shaking the poorly made college bunkbeds. The second most important reason why college students should have separate beds. The most important reason would be the story every college tells you about the star student/athlete that fell off the top bunk and got paralyzed and almost flunked out.

Fuzzy has bedtime blunders.
