Back Flush

Mostly used in the fag community, it is where two men touch their penises together so the pee holes line up and the fore skin is pulled together ( best with one uncircumcised penis and one circumcised ) Then they piss inside of each other's pee hole thus back flushing the penis.

Hey bro, you wanna back flush each other tonight after dinner.

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..."

Flash back fuck 

Well having some good old fashioned intercourse throw ur partner for a loop and slap them and attacking them screaming they’re in the trees. Then proceed to nut on them using your penis as a powerful machine gun.

Yeah I pulled a flash back fuck on my girlfriend and now she’s in the hospital.

When you, with out realizing it, think about memories. They maybe good or bad. When using it in a sentence, use it as you were talking about a town or city.

Hello? Hello? ( your talking to your friend)

Oh! Sorry! I just was on my way back from Flash Back Town!

backflush 

The turds/toilet paper that always manage to scoot back into the toilet bowl at the end of a flush.

I had to flush the toilet 2 times at work today because of the damn backflush.
