Inserting drugs or having someone insert drugs into your body through your anus. Better experience is allowing someone to blow the substance inside you with a straw.
I had Stover blow cocaine in my ass last night to achieve the best high. Hit her up...she's boofing everyone!
Common slang term used for anal sex in the 1980's. More recently used to describe the act of inserting drugs ( most often tab form or powdered ecstasy) through the anus to more quickly enter the blood stream, also referred to as "thumbing" or "booty popping"
