unfun 

the evil opposite of fun. That which more approximates work, school, hell. The antithesis of a good time. Boring. Monotonous. Drudgery. Lifeless, limp, lame. No Fun.

Manufacturing widgets for Mr. Wanker's Widget factory is way unfun.

unfun 

1. the feeling you get when you are working in a building where no one likes you anymore, after disagreeing with co-workers they become subversive and underhanded and stop talking to you

2. how your life feels when you fuck up an affair you are having with the most wonderful, exciting, fascinating, beautiful person you have ever met in your whole life because you can't get your shit together, totally unfun

"Hey JP, no one wants you at the meeting, and you have been uninvited to cookie time, sorry man."

"You know, working in this building is unfun"

Unfrungulate 

To not be able to think of a word so you just make up some slightly sexual sounding bullshit.

It was on a live-stream, which meant that you got to see the unbridled, unfettered, eh... un.... unfrungulated....
