Flashfuck

1. Sex so fast that you don't even realize it's over when she's already dressed and leaving.

2. A flashbang grenade.

"That wasn't even 5 mintues"
*door slams, man looks around confused*
"Was that a flashfuck?"

flushstrated

the feeling you get when, after flushing your toilet, your waste remains.

I pushed the toilet handle and when I looked back it was all still there, and I felt incredibly flushstrated.

flash cleavage

The phenomenon that occurs when photos are taken at the optimal position on the z plane in relation to cleavage to give the illusion of 1.5x - 3.0x the actual cleavage. This is mostly done by illuminating the front of the cleavage and casting shadows on the back and/or top of the cleavage, thereby creating the affect of depth, volume, and possibly atmospheric perspective.

*Note: photos w/ flash cleavage are 12x more likely to be posted on the internet by the cleavage owner; who will then pretend to not know what you are talking about approximately 100% of the time.

Matt: dude here's a pic of that girl Madison I met at the club...
Tyler: bro am I detecting boob job???
Matt: ...nahnahnah, there's just maximum flash cleavage there.
Jeremi: nice bro.

Flashes

Fake eyelashes applied with lots of makeup as to cover a man or woman's lack of eyelashes or short eyelashes as well as showcase their inner diva.
Mainly used by urban tribes in the nightlife despite the fact flashes are extremely uncomfortable, noticeable and come off periodically from sweating, movement or the use of the crappy non-stick adhesive which comes in every box of flashes.

"hold my flashes while I slap this bitch."

I can't see anything through my flashes, meaning they're definitely on and I'm looking spicy.

Flashlight

When it's dark outside and the blunt you're smoking shines bright and the embers glowing make it look like a flashlight

That L lowkey looks like a flashlight in the dark.

Brown Flash

In the oscillations between struggling not to shit and feeling perfectly fine (somewhat analogous to contractions during child birth), the brown flash is the temporary but dire need to take a shit. Often results in sweating, heavy breathing, and a clenching shut of the asshole to prevent shitflow.

After 2 hours of holding in a shit I was brown flashing incredibly hard. My feelings of intense need to shit were becoming closer and closer together and I knew if I did not shit soon I would ruin a pair of innocent underwear.
