1. (adj) Fucked Up for Free (This is notably different than fucked up for fun, as being fucked up for fun usually costs money, and there are specific guidelines to what can be classified as fucked up for free.). In order to be FUFF'd, the following criteria must be met:
1. The substance in question must be procured free of charge (i.e. found, stolen, or given to the person)
2. The person must use the substance to achieve an altered state of consciousness.
