Crank

1. the cranks of a crankset on a bicycle, where the front gear set is as well as where the pedals are attached to. 2. The entire crankset of a bicycle will sometimes be referred to being "the cranks" or even just the "crank." 3. Methamphetamine, many places "crank" only refers to what is known as "peanut butter crank" which is a product that is pretty much no longer around as the availability of the substances used to make it are more heavily regulated than they used to be, often used to contrast it from the currently available (and widespread) crystalized methamphetamine. In many places, such as Contra Costa County, California it is used to refer to what is elsewhere known exclusively as "crystal meth" often as the term that is used by the rougher more criminal lifestyle crowd while the lighter more "party" crowd will refer to it as "crys" or "meth." In such places to contrast the old product with the current one the whole term "PeanutButter crank" would have to be used. 4. Combination of "cry" and "wank." Someone in a sad state (likely after a break up) to where they are horny while feeling like they are down on their luck enough to where they would cry. Likely more of an activity that will be referenced to more than it ever actually happens.
