To go in for a fist touch, but stopping midway, yelling "JELLYFISH!" and propell your hand backward like that of the movement of a jellyfish.
Other variations of this would be snowman, in which you place your fists ontop and bottom of the other persons fists, snail, in which you slide your hand onder theres with two fingers up, and turkey, where, during a high five, you but your thumb out and slam your fist into their palm so that it resembles a turkey.

When you finish having sex with a girl and realise post-coitus the condom has been left inside her. In a haze of panic and confusion you use your index and middle finger to fish it out in a semi-sensual style. What you end up pulling out should look like a shrivelled old jellyfish, hence the term "Jellyfishing".
When Matt realised his vigorous love making and oversized condom had resulted in the rubber slipping off, he kissed Lisa while jellyfishing.
He eventually came up with the goods and then prayed she was not pregnant for the next few months.
