In the end, though, there is one sure way to distinguish a real hippie from his assorted sympathizers: hippies drop acid. That is, real hippies frequently, if irregularly, ingest LSD.

Phenidic acid, or Ritalinic Acid, or Evitalinic Acid is a portmanteau of 2-{Phen}yl-2-(p{i}peri{d}in-2-yl) acet{ic} {acid}. It is used to make Methylphenidate (Ritalin) and Ethylphenidate (Evitalin) by reacting it with methanol and ethanol. 2-Phenyl-2-(piperidin-2-yl) acetic acid is awesome!
Steve: I reacted Phenidic acid and Methanol to make Methylphenidate (Ritalin). I used the rest of the Phenidic acid to make Ethylphenidate (Evitalin).

A form of Diarrhea that burns like fire, often due to excessive wiping necessitated by frequent gastrointestinal distress, spicy foods which leave behind residue on the sensitive tissue of the anus, or food processing too quickly through the digestive system and thus the stomach acid not being neutralized like it normally would and acid being present on the anus (with a severe burning sensation similar to acid reflex disease, or heartburn). Often times a combination of factors and the fact that excess human excrement and excess acid from the stomach normally found in diarrhea burn the anus area, and makes it feel as if it's being eaten away and disintegrated by acid. Also accompanied by "sharts", especially minor one's that only leak out a small amount but create the similar burning sensation.
Whatever the case, it burns like fucking hell.
