Meth amphetamine, aka CRANK is called Crank because it cranks you up, you are driven, full of energy, cranked up, like the volume on a radio, full blast, to the maximum. The idea that the drug is called Crank because it was smuggled in crank cases of vehicles is so ridiculous it is laughable. How much Crank do you think you could stash in the crank case of any vehicle, much less a motorcycle? Half a gram? What? And what do you suppose you would contain the meth in? Pour it into the oil, and then somehow retrieve it through chemical processes? Only a spun-out meth-head would buy into that belief. Ludicrous!
I did some crank and haven't slept in 3 days.
