the opposite of catfishing. someone who seems bland and simple on social media but stings you with so much more sexiness in person.
Guy 1: Dude, remember that Ashley girl I showed you on Tinder? Probably not because her profile sucked. Well, last night I met up with her and she was SO HOT! Totally knocked me off my feet.
Guy 2: Now THAT is what I call jellyfishing!

One of the most annoying things on planet earth. They have jiggly bodies and tentecles that they sting you with. The deadly ones near Austrailia like the box jellyfish can kill you within 10 minutes, but the common ones nears the USA aren't that dangerous but when they sting you it itches like there's no tomorrow.

A fetus. A collection of cells sucking nutrients out of it's host, and the umbilical cord (belly button) is essentially both your mouth and anus, just like a jellyfish. Thus vampire jellyfish.
The baby is at that vampire jellyfish stage, we don't really know what it is it's just the blood sucker.

"That's funny it moves when you move."
"Really?"
