Euphemism for masturbation. Combines a verbal allusion (jacking off) with a
classic literary allusion (Jack and the Beanstalk).
Variant: "jacking the beanstalk" This variant makes use of the full,
proper gerund suffix of ing - making it the preferred usage form in public and at formal gatherings, including at work,
holiday and family celebrations, and when talking with grandparents, priests, co-workers, neighbors, and medical professionals such as doctors and nurses.
Ex: I don't know why Eriq doesn't lock his
door; this is the 10th
time I've walked in on him while he was hunched over the
computer jackin' the beanstalk.
Ex. She's out of town, so I've taken matters into my own hands and been jackin' the beanstalk like a shedevil in heat.
