The act in which a man lies on his back as a girl sits reverse cowboy position on his face as he performs cunnilingus. The 'jellyfish' part comes in as the girl flails around as if she were a jellyfish when she climaxes. Usually done in orgies as it's not a physically tasking position for either participant, leaving both extra energy to continue in orgy activities.
John: 'Yo, me and dis bitch tried jellyfishing last night. It was the shit!'
Fred: 'Fuck yeah, I gotta get my girl to try that shit'

when you get drunk or high and float in a pool inside a ring float. u let your legs dangle underneath you like a jellyfish and u let your face lay restlessly on the float. if done right it is the most effortless thing you can do.. even more so than laying down
yo last night after we blazed we all went jellyfishing in the pool. it was just way too relaxing
