Same as jacking off, but in addition: Any time a mechanical device is temporarily malfunctioning, especially in an erratic motion fashion, it is beating off. See also on the rag
for malfunctions of a 5-7 day nature
Bill, the tachometer in you GTO is beating off. (wiggling erratically between 1400 and 3600 RPM)
, beating off is the same as jacking off but it seems to sound more harsh when u say beating rather then jacking
i love to beat off in wierd places
When you're doing something musically and accidental get off beat.
Tim: "*1-2, 1-2, 1--2*"
Jon: "Wow Tim, you're really beating off!"
