The art of performing oral sex or a hand-job to sleeping man without causing him to wake. A proper magic jack should involve clean-up as well, leaving the reciepient all but unknowing of the night's transgressions.
I woke up feeling great this morning, even after 16 Budweisers and a handle of Beam. On cloud nine all day, couldn't figure it out. Then my girl told me she magic jacked me after I passed out last night! Mystery solved!
