The art form of taking random objects found on the streets or peoples' trash like old t.v.s and dehumidifiers and putting them in a persons yard. You could put signs from main roads or from other peoples yards. Also, you could add some construction cones or random poles and such. Use whatever fuels your fire. You can spook a person you like or don't like, however, make sure that they will get mad if someone spooks their yard. Its more fun that way! :)
Man we went spookin last night and spooked Drew's house real good! Its all over facebook!
