When a person puts a hand in for a high five, but just before the kill, the giver of the high five wriggles their hand away, and annoyingly shouts "jellyfish!"
Jill went to high five Matt as congratulations, then she Jellyfished him.

N., a statement that sounds like a compliment but, the more you think about it, the more it stings like an insult. So named because, like a jellyfish, you don't feel it at first, but the longer you leave it on, the more it stings.
Chick #1: She was like, "You actually look nice today," and I was like, "Thanks." But then I'm like, what the fuck was the purpose of "actually"? Was she saying I don't usually look nice?
Chick #2: She said a total jellyfish to you, bitch.

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.
FIST TOUCH! *goes in* *Stops* NOPE! JELLYFISH! *goes backwards*
