completion 

the finishing of an gigantic square pyramid consisting of 22 bricks, but must be at over 9000's stories high.

Completion cannnot be completed because it is completely unneccessary!

Completion Day

The first day in a girl's life when she gives head to completion.

It took twenty years, but it was finally completion day on February 4th when she finished the job.

completion envy 

The feeling someone with a large gaming backlog (A.K.A. pile of shame) gets when they hear about others who play multiple games to completion.

You're adding to my completion envy!
This isn't helping my completion envy.

to completion

To the point of climax or ejaculation.

I gave him a blowjob to completion, then gobbled his load.

My date sucked me to completion, then gobbled my load.

Post Completion Depression 

When something that you have put a lot of time into recently is finally over (like the finale to a tv series that you love, or the end of a great video game trilogy) you are sometimes left melancholy, and with a feeling of "what do I do now". This lingering sadness is called "Post Completion Depression", though it's often shortened to P.C.D.

Anime enthusiast: So have you finished watching Kill la Kill yet!?
Casual anime fan: Yeah, it was great, in fact, I think I'm starting to get Post Completion Depression.
