An evening consisting of gentlemen whom are close friends that go out on the town, consume large quantities of alcohol while yelling out the term "Dude's night out!" through out the whole evening. Usually led by a man with a lisp carrying a clip board. Quite often the majority of the group members tend to be of Portuguese decent and smelling of a mixture between that of Cool Water cologne and chouriço.
"You know what tonight is?!...Dude's night out!!"

"Hey man, you coming out for "Dude's night out Friday?!"

"What happens on Dude's night out, stays at Dude's night out!"
