fun
1. A source of amusement, joy or pleasure. Something that will make you go "wheeeeeeeeee" with your hands in the air.

2. NEW YORK CITY, DISNEYLAND AND CEDAR POINT. WEEEEEEEEE!

3. Something that I don't have enough of.
Being broke, going to college, having responsibility after responsibility takes away time to have fun. And you will end up being one of those people that when you do do something fun, you will act out the worst making other people look at you and say "She don't get out much."

Actually a pretty awesome band.
They're made up of Nate Ruess, Andrew Dost, and Jack Antonoff.
A lot of people are really quick to judge them because of Some Nights and We are Young.
But really, there's so much more to fun., like their '09 album, Aim and Ignite.
Even if you aren't in to "mainstream" music, I'm sure these boys will have a song or two that will make your feels explode.
Hey man, Some nights is so gay.

Maybe but have you heard Walking the Dog?

Wow this is actually a great song! I'm sorry for judging fun.!
