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.

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.

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.

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.

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.
