flashaholic 

Somebody who is really addicted to flashlights.

A typical flashaholic might have dozens of them; hardcore flashaholics might have hundreds or (in one documented case) close to 1,500 of the bright little suckers!!!
The word was coined a number of years ago on a BBS about flashlights.

Hey Josh!
Did you hear that Craig is a true flashaholic, with 1,497 flashlights, lasers, and other assorted things that flash, blink, or otherwise emit EM radiation in the range of 380nm to 780nm?
What a kick in the head!!!

Flask Beard 

A person or people who accompany somebody who is too cheap to buy his own drinks at a bar and instead brings a flask of alcohol and orders soft drinks. The "flask beards" accompany the flask-bearer, ordering enough alcoholic drinks to disguise the fact that the flask-bearer is totally dumping outside liquor in his diet Coke. Typically the flask-bearer compensates his flask beards at a rate of about 25%, which provides incentive for the flask beards.

Kevin wanted to bring a flask of vodka to the bars on Saturday so he could save money by ordering only orange juice all night. To avoid detection, he recruited Pete and Bob to be his flask beards, so he would avoid detection.

Multi-flasking 

A phenomena in which everyone on the ski lift has a flask of booze and shares it with the rest of the chair.

G: Dude, why is your bloody leg bone sticking out of your ski pants like that?
B: No idea dude, it might have been the multi-flasking I indulged in prior to the bunny hill.

Person 2: “I know right! One time I was trying write an essay and this mf looks at it in 3 seconds and then pulls out a 5 page lecture about how bad it is before I even started writing it!”

flakka 

A name created to try and push the drug a-PVP onto the streets, a strong stimulant with effects said to comparable to a cross of meth and coke. Much like MDPV. Currently bulk synthed in China and imported.
You can eat it, snort it, rub it on your gums, smoke it in a meth pipe, inject into a cock vein and also booty shoot it.
Incredibly potent, dangerously cheap and more addictive than meth. So have fun kids :)
