DNO stands for Dudes Night Out. These occur once every 2-3 months. They usually occur when some bros just want to chill on a Sunday night. The DNO can start with a few beers and will end with what ever the best movie in theaters is. DNO's can not involve women in anyway what so ever.

Dude 2: Wow he would, I can't believe he ruined it.
