Get the runs/running off at the mouth mug.
To masturbate, usually referring to guys only. The term is used when a guy has the urge to whack it after seeing a hot girl.
I was dancing with this hot chick at the club, but I didn't go home with her. When I got home, I was so horny that I had to run one off.
