When an individual, usually college age politely requests for his/her roommate to leave the room for an hour so that he/she may masturbate without worrying about being walked in on, thereby enjoying the privacy and peace of mind needed for a good masturbation session.
Dude, it was like 4 in the afternoon and I was doing my work when my roommate barged in and told me to leave the room because he needed his erwin time.

The first time he had erwin time in a month, Derek squirted such a big load that he ended up needing to clean his keyboard and his whole desk area

She hadn't been with a guy in like three months so she decided to go erwin time on her roommate
