The Taint Joint is something only passed off upon someone in ill will. Marijuana is rolled into a cigarette also commonly know as a joint, later the joint is placed along the taint, secured for a time underneath the sweaty scrotum. Later this joint is given to an unsuspecting victim who in turn later smokes your sweaty taint grease.
A small joint in which a filter is rolled and marijuana is put in the tip of the filter and hit like a one hitter. Reported to get the average person higher than normal because of the close contact of the marijuana to the mouth. The shorter distance allows less THC to be wasted, hence the reason a filter is used.
