Any junkie who has been using needles so long that they have blown out all of their veins and now must break the tip off of the needle and squirt their dope (heroin, cocaine, meth, oxys...whatever their drug of choice is) up their ass to get high. This is usually followed by the person shitting his/herself and is pretty amusing to watch.
Junkie #1: I love to turkey baste my dope but i hate cleaning the shit off my leg when I am done.
Junkie #2: That is why I turkey baste over the toilet man, no mess to clean up.
It is so sad to see Randy now, I hear that he is a turkey baster. He is wasting his life shooting meth up his ass.
