Unofficial 

Short for Unofficial St. Patrick's Day, this is an event held each March at the University of Illinois at Urbana-Champaign. This is the largest local drinking holiday in the United States. It was created due to St. Patrick's Day being held over U of I's spring break. Students from across the country visit Champaign-Urbana to take part in this, as their schools do not consume as much in an entire decade as U of I does on Unofficial.

"Dude, don't you love going to IU?" - Indiana Student 1

"No, I am going to U of I this weekend to celebrate Unofficial. I wish I had gotten good enough grades to get in there." - Indiana Student 2

"Yeah, you're right. They are better at academics, athletics, AND they have way more fun." - Indiana Student 1

unofficial 

Unofficial is the phrase commonly used to describe the Friday prior to St. Patrick's day at The University of Illinois. The holiday began when students realized St. Patrick's Day was falling on spring break and they would not be able to celebrate it. The day is marked by bars opening at 8 in the morning, kegs on front lawns, students from nearly all surrounding schools flooding the campus to celebrate by drinking obscene amounts of alcohol. It has been said that more drinking occurs on Unofficial at U of I than occurs at many other school's entire years.

Oh man, I got so bellig on Unofficial last year.

Unofficial Girlfriend 

The term unofficial girlfriend is used to describe the female partner in the relationship when neither of the people in the relationship have made it official. The term unofficial girlfriend is used to show you intend to make said girl your girlfriend at some point. If you have an unofficial girlfriend you may act and speak as if she is your girlfriend but technically she is not. Exclusivity with unofficial girlfriends is optional, unlike with official ones.

“I will ask her out eventually but for now she is my unofficial girlfriend”
