Jim-Bobbing
To masturbate with your wrists tied together, sometimes alternating between hands or using both at the same time. Named after Jim-Bob Duggar for tying his sons hands together as a masturbation punishment.
I have horrible rope burn from my Jim-Bobbing session last night, but you just can't beat that two handed vice-grip finish.
