Acetone Peroxide 

An very sensitive yet powerful explosive. Common applications include a really cool-looking cloud of dust (yay!) and setting off even more powerful explosives. Referred to as AP.

Be careful using the acronym AP at school because it also stands for Advanced Placement which is something completely different :P

It's also dangerous to make if you're not being careful.
Guy 1: Why is there a hole in my basement?
Guy 2: I messing around with some AP...
Guy 1: Advanced Placement?
Guy 2: No, Acetone Peroxide. Why would a test blow a hole in your basement?

acetone wash 

An "Acetone Wash" is one method used by cocaine users to purify cocaine purchased on the streets. Each time the smuggled cocaine switches hands it is almost always cut or "stepped on" resulting in lower purity & even the possibility of dangerous cutting agents by the time it reaches the users. To achieve a purer cocaine base & eliminate these cutting agents many users "wash" the cocaine with 100% anhydrous acetone. Depending on the cut an acetone wash can also be used in conjunction with other purifying methods. After "washing", the cocaine base can be smoked or converted back to powdered cocaine HCI using muriatic acid. There are several "washing" methods outlined on the internet and some require highly flammable and explosive chemicals such as ether. Due to this risk many prefer acetone as a safer and as effective alternative.
By performing an acetone wash John eliminated many of the impurities in his cocaine.

Acetone is the organic compound with the formula OC(CH3)2. It is a colorless, mobile, flammable liquid and the simplest example of the ketones. Often used for its flammability by pyromaniacs and/or pyrotechnics. (But just because you use it doesn't mean you are one.)
Bystander: Are you buying acetone?
Pyrotechnic: I'm... using it as... paint remover?

Bystander: What are you doing with that acetone?
Exasperated bystander: Some idiot bought it as paint remover and almost burned the house down, I'm getting rid of it.
Acetone by Inferno&Anarchy May 18, 2010
A highly flammable acid commonly used by people even though contact with eyes, skin and lungs/inhaling is very bad for you. A better solution to this when used on nails is to summon any dark evil and sacrifice your soul in exchange for instant, perfect removal of polish.
She/he/they used acetone to remove her/his/their nail polish.
Acetone by ACID FLAMINGO November 6, 2018
A great legal high. It is found at the beauty supply store, and can seem like innocent nail polish remover, and that's what its sold under. If you sniff it, you get little high. If you inject it into yourself, it feels waaaaaaaaay good. I mean, like so fuckin high. It feels even better than heroin. It makes your nerves a little more sensitive, and it is a great sexual high. It makes life make sense, and everything seems blended around the edges. The only downside: do not use it if you don't like needles.
I got high on acetone, and then i ripped of his clothes.
acetone by Jace Noelle March 11, 2007
Meaning to finger a girl. Used chiefly in nail polish remover and varnishes, as a general solvent, Acetone is a less vulgar reference to the word finger, derived from the fact that it is a key ingredient in the product of nail polish remover.
'Hey Brad, I saw you with your hand down Laura's jeans, anything happen?'

Surf Dracula Syndrome 

A phenomenon in film/television series, most notably streaming series, where the main premise is drawn out to such a point that it takes an entire season or more to get the parts of the series the audience is actually interested in seeing.

For example, if a series is titled "Surf Dracula," a majority of viewers would tune in expecting to see Dracula surfing by the first or second episode. However, the entire first season would instead be tedious padding and backstory before finally ending with Dracula surfing in the last five minutes of the season finale.
I watched "Smallville" on Netflix the other day. Dude, it was ten seasons of filler before he finally flew! Major Surf Dracula Syndrome!
