un-fun-ness 

The complete abscence of any fun or the action of having fun. Can apply to students suffering from abnormal amounts of tests and homework.

Can we change the subject to something more fun to take our munds off the un-fun-ness?

Un-funnities

I wanted to go to the movies but I had a long list of un-funnities to get through first.

f.un 

on the Gorillaz-Unofficial Mb, users write f.un because if they type in "fun", the word filter will automatically change it to fuck.

can also be written fu.n, fu*n, f~un.. etc.

User 1: why do you guys always put dots in the word fuck?
User 1: oh.
User 2: f.un times
