Masturbation. The act of pleasuring oneself using manual stimulation. One handed-tussle. A less aggressive version of the 5 knuckle shuffle and cousin to the 2 hand tango. A fistful of man dollars. Pulling on the old wad. Jerkin' the gherkin'. Slapping the ham. Pounding the pig. Pullin' the skin flute. One hand short of a 2 hand tango.
After yet another unsuccessful night out, John went home alone and was reduced to doing the old 1 hand waltz.
