Black Flash! 

The name of an attack from animanga series 'Jujutsu Kaisen.' A Black Flash is a distortion in space that occurs when a sorcerers cursed energy is applied within 0.000001 seconds of a physical hit. When a sorcerer is able to do this, their cursed energy flashes black, and the force and strength of their strike is equal to a normal hit amplified to the power of 2.5.

Gojo Satoru: "Ya know. That "Red" just now... Still hasn't exploded.
Ryomen Sukuna: "Gah! From behind me..?!"
Gojo Satoru: "BLACK FLASH!"

Black Flash 

Term coming in its definition from the slang of the anime and manga series "Jujutsu Kaisen", written by the author Gege Akutami, is a phenomenon that occurs when cursed energy is applied 0.000001 seconds before a physical hit, in order to put it into perspective, a "Black Flash" can result in being thought of as a kind of "critical hit"

According to this sense, it could be perceived as something as "When you do anything that is recognized as remotely rare on its probably to occur and also during a considerated short period of time", while being said in reference to the original term.

An example from it could be something in the lines of:

"X" Person: "Hey yoo man, me and my homie just hit the sickest and cleanest dab me up from all time!"
"Z" Person: "Really? in that case I do believe that you and your friend just did the equivalent of hitting a Black Flash in real life"

Fuck Flash Back (FFB)

Fuck Flash Back... you just fucked some chick the other night, while you were off your fucking face.. then, when your mind wanders...
BAM. FFB...

the mind shows scenes of embarrassing facial expressions, slips, trips, falls..
maybe even the cum face... if you were lucky...

most likely to strike whilst at your shit job, or at a boring meal with the rentals. The physical reaction to the FFB manifests itself in the facial area, and prompts others to ask what is the matter with you...

"oh man, i gotta “Fuck Flash Back (FFB)” with the rentals at dinner last night"
"oh shit what did ya mom say?"
"she told me if i didnt like the food i should go to mcdonalds."

“Fuck Flash Back (FFB)” strikes at work:
*screws face at thought*
"andy....are you ok? did you hurt yourself?"
"erm... yeh..."
