Slang term for caffeine, usually in reference to snorting or insufflating the caffeine powder. Used when in need of a quick rush, without much of a euphoria. Also called by friends as yellow 50/200 (In reference to snorting 1/4 or complete double strength Jet Alert pill) or yellow snow or snow flour (Used as a safe word when trying to say snorting caffeine but are in public areas or places when doing this is frowned upon) The results of snorting caffeine are a strong rush and focus, little to no euphoric affects (it depends on the person), and a short burning feeling in the nose. Great if you are going to or at a party and need some energy and are out of coke.
