Uncummable

When you're trying to make someone cum and you're doing everything that you can and using every trick in the book and they just can't/won't cum

I went down on a chick for two fucking hours and she just didn't cum.

She's "Uncummable"

unsgummable 

Litteraly: Subtle, difficult to detect, sneaky.
Often used with sarcasm - "easy to detect", "evident", touchless"

From the Venetian verb "sgammar", litteraly "to find someone out" and "un" negative.

If someone is doing something wrong hoping to be unseen but you and maybe others notice it, you say loud "unsgammable"

If you approach a girl with a bottle of Jägermeister is not unsgummable that you want her drunk.

If you come home 5 a.m. slamming the door and puking everywhere your drunkness is definetely sgummable!

uncumable 

When one is, through possible over-indulgence of various substances, or by simply being a master in the art of ass-tappery, unable to cum despite trying incessantly.

One of the two different categories of whiskey dick, one a dysfunctional penis, the other, and overly functional dick.

"Dude she thinks I'm a god of the dick, I was uncumable"
