sketch walk 

After the consumption of at least (2 1/2) Pills of Ecstacy (or any upper abused accordingly) a sketch walk can occur. During this walk, you must talk to and make uncomfortable at least (1) person you see on the street or working retail. Additionally, during the early sketch walks the person would notice something was amiss with the people he was conversing with (us) as they were visably on DRUGS.

Yo' Paul, wanna go on a sketch walk and scare some old people at a convention hall?
