anagram for "potheads with a purpose." refers to marijuana smokers who make a habit of going on madcap adventures after smoking. Possible activities include: organizing a scavanger hunt, driving into the city, going to the library, running numbers at a
local grocery store, glamour bombing, breaking into vacant commercial spaces and organizing a sort of club-house, people watching at your town
square, hiking through your favorite
forest reserve. You get the idea.
