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.

Fast candies

Originated from a YouTube video named “FAST CANDIES 3AM CHALLENGE” or smth
The YouTuber Marcello_timenice_30 or the voice of Bambi Bambi Bambi made a joke to add to the funny of the video where instead of pronouncing “candies” he said fast food and stuttered replacing it with “fast candies”

It was later used by cynda & granarte for the Friday night funkin song “sugar rush” where the oppoent (bandu) says YO WHATS UP GUYS TODAY WE'RE DOING FAST FOOD- I MEAN, FAST CANDIES, DEZZ CANDIES, DEEZ FUCKIN CANDIES

Bandu: YO WHATS UP GUYS TODAY WE'RE DOIN
Bandu: FAST FOOD- I MEAN
Bandu: FAST CANDIES. DEEZ CANDIES
**wrapper oppening**
DEEZ FUCKIN CANDIES

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”

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.
