The figurative bad guy who constantly dries your body out as you sleep after a night of heavy drinking, causing you to wake up every half hour or so feeling like you're stranded in the middle of the desert. You chug as much water (or any available liquid that's hopefully not more booze) as you can, and go back to sleep, and soon wake up gasping for more water and needing to urinate as well. This is because Dehydro is much better at drying you out than the water is at rehydrating you.

If you are so drunk that you manage to sleep through the night, Dehydro teams up with the toxins in your blood stream to give you a hangover worse than death.
Dehydro was a real bastard last night. I hardly got any sleep at all.

7,8-Dihydroxyflavone 

7,8-dihydroxyflavone (Tropoflavin) is a supplement that is an antioxidant. It has also been found to act as a potent and selective small-molecule agonist of the tropomyosin receptor kinase B (TrkB), the main signaling receptor of the neurotrophin brain-derived neurotrophic factor (BDNF). In addition, tropoflavin possesses powerful antioxidant activity independent of its actions on the TrkB receptor, and protects against glutamate-induced excitotoxicity, 6-hydroxydopamine-induced dopaminergic neurotoxicity,28 and oxidative stress-induced genotoxicity. It was also found to block methamphetamine-induced dopaminergic neurotoxicity, an effect which, in contrast to the preceding, was found to be TrkB-dependent. 7,8-dihydroxyflavone protects against stimulant induced glutamate exitotoxicity and dopaminergic neurotoxicity. By stacking amphetamine or other stimulants with Tropoflavin, you can prevent brain damage. However, you can't prevent cardiotoxicity. So choose a less cardiotoxic stimulant like amphetamine, Ritalin, caffeine, or EthylAmphetamine, or Modafinil, the wakefulness enhancer, instead of choosing more cardiotoxic stimulants like crack. Crack is wack, speed(amphetamine, EthylAmphetamine) will help me succeed
I stacked 25mg EthylAmphetamine with 25mg 7,8-Dihydroxyflavone and I prevented brain damage. Tropoflavin is awesome!

dihydrogen monoxide 

dihydrogen monoxide: It's more commonly known as water. You know, the substance that every single living being relies on to survive? The origins of this item are multifold, from flyers circulated at the University of California at Santa Cruz in 1989 (so 20th century!) to a junior high school student who surveyed 50 classmates in 1997 and got 43 of them to sign his petition to ban the chemical. He then won a prize at his science fair for his project, called "How Gullible Are We?" Several Web pages touting the chemical's dangers are still live. Don't feel too bad if you've ever fallen victim to this hoax; even a government official in New Zealand took the bait last year.

trucker's tan 

A sunburn or suntan focused on the left arm. It is caused by the left side of the body being the only half that gets exposed to sunlight while driving. Presumably, it would be located on the right side of the body in countries where they drive on the left side of the road.

British slang for a scientist or technical expert, esp . when the speaker is not certain of the expert’s specific field of study. Not necessarily derogatory, but typically used by persons without a technical background. In the US, the equivalent would be “egghead”, “squint”, or “geek.”

Origin of the word is unknown. Started sometime in World War 2. Given the typical evolution of British slang, could easily have started because what these experts did was confusing or “baffling” to the common person.
According to the boffins downstairs, the murderer used a serrated blade.
