smoothening 

When EC2 Spot, Amazon's spare capacity compute at a discount, switched from bidding to max price. Cost-per-hour and instance interruptions both got smoother. Spot users were, and still are, as smooth as possible. Coined by an appreciative (and marginally hilarious) customer.

After The Smoothening, EC2 Spot customers saved even more on their cloud computing without even trying.

nutt smothering 

During mutual oral sex or "69ing" with the male on top, testicles drape over the nose of the partner on the bottom, covering the nostrils and impeding airflow.

Damn, when I was 69ing that bitch, I gave her such a nutt smothering that almost passed out.

smothering majora

Your significant other is snoring too hard or passes out early. You ride the face until he/she starts passing out. Once the convulsions start, then You step on their junk to revive them.

Todd snored so hard he deserved a smothering majora from his wife as retaliation for the gladiator helmet she received once.

smoothing the cat 

1. When a girl shaves her pubic region.

2. Also apparently just a west country term for stroking your cat but that's no fun.

1. "I pulled this girl last night, I was so glad she had recently smoothed the cat before I went down on her"

Shirley "Are we gonna try and pull tonight?"
Cherish "Yeah"
Shirley "Best get smoothing the cat then"

2. "I love smoothing our new cat"

smoothing one out 

To "smooth out" one's erection
To masturbrate as a male
To jack off

So I was in my room smoothing one out when my mom walked in...
