slow-fast

When you are using a lot of energy and feel like you should be moving fast, but you're still moving slow.

"Man, I was walking home today and I was goin slow-fast."

Sinking Fast

Originated from the Titanic disaster, a very British expression to describe a disastrous situation that is rapidly worsening, heading straight and quick to an inevitable disaster with no possibility of a any positive outcome to the degree that there is no point in even trying to save the situation.

I've had a look at the sales figures, Debenhams is sinking fast.
Terry was diagnosed with stage 4 lung cancer, he is sinking fast.

Fast Sunglasses

Those sunglasses that middle aged dudes wear in their Facebook profile picture (and everywhere else). They are extremely aerodynamic, and look like they are built for speed.

“Hey man, I think I’m going to go to Home Depot”
“Don’t forget your Fast Sunglasses”

“I saw so many Fast Sunglasses at the antique show today”

fast flap

That piece of extra skin that hangs down from a domestic or wild cat's belly. Some say it is to help the cat run faster. This loose flap of skin on the abdomen helps the cat stretch out further with each stride. Some say it is extra skin in case the cat has to binge eat and store extra fat in the wild.

The bengal's fast flap helps it run faster, up to 30 miles per hour.
