e-fenestration 

Accidentally alt-tabbing to an equally inappropriate window when your boss/parent suddenly appears.

Man, I had like...15 windows open on my PC at work today and only one of them was the report I was meant to be working on. Clicked from Facebook straight to YouTube when my boss appeared. Just a big-arse kitten playing a piano on my screen. Complete e-fenestration.

The Fenestration Paradox 

The burning need (whilst stoned) to both lie down, get up and eat something, drinking something and play more Mario. This creates the ultimate paradox in that you can never be doing what you want to, despite attempting to do what you need constantly.

Mobile Oral Fenestration 

Giving/receiving head though the window of two vehicles that are side by side as they are driving down the road. Done in vehicles like school buses or vans.

Paul took out his dick and the jot girl in the bus next to us started giving him mobile oral fenestration.

Penestration 

To become frustrated from the inability to penetrate or be penetrated sexually.

Despite copius amounts of lubricant, Carl's fat, girthy cock was simply to big to cram into Dana's tight bung hole. After an hour of trying, they both gave up feeling nothing but penestration.

Funstration 

The act of something being fun and frustrating at the same time.

Getting the 200 flying rats in Grand theft auto 4 is a big pile of funstration.

festration 

The nostalgic longing to be at or on one's way to a music festival, preferably one far away from the responsibilities, stress, angst and conflict of the straight world. This feeling may be simultaneously eased and provoked by consuming festival recap videos, DJ sets, scouring set lists and/or by planning for your next festival.

I'm feeling an acute sense of festration right now! I'm so festrated!
