Processed meat
The act of masturbating, but instead of already being horny and just feeling like a wank, you have to touch yourself a lot just to achieve a boner. Thus, the achievement of an erection and subsequent ejaculation is wholly manufactured and processed, unlike the natural, and far more common "horny wank", customarily used to alleviate "blue balls". This processed meat is often called a "cold wank".
