Spirum is the feeling you get when tripping on LSD or magic mushrooms when you think your coming down or leveling out off the trip than suddenly BAM and your tripping again, spirum can last up to a quarter of an hour, witch can be dangerous because you might think about taking more. The word spirum originated in the southwest of England in 1996 in a shed whilst tripping on mushrooms.
