A unit of erectile strength that determines the intensity of an erection. A Roche unit of 0 means that the penis is perpendicular to the testicles, while a Roche unit of -10 indicates severe erectile dysfunction (see floppulant). A Roche unit of 10 means that vigorous masturbation is necessary to prevent irreparable damage to the phallus.
This girl was SO fine man, you won't even BELIEVE. I was walking around with a 8 Roche unit erection for weeks. Gotta get with that, ya' heard?
