Usually occurs when laying on one's back when wrapped in blanket so that only their head is shown; blanket is also tucked under their feet and under arms. Looks like one is making a cocoon as butterflies would.
Girl walks into living room where she see's her sister watching tv, tightly cuddled into a blanket.

Girl: "Aw, look at you all nestled up there."
Sister: "Yeah, im cocooning, it's the best way to keep warm."

retreating to the seclusion of your home (as for privacy or escape)
I put on my favorite bulky clothes and laid on the sofa for hours. I was cocooning because I did not want to be bothered by anyone today.

When someone excludes themselves from society and attempts to improve on a certain factor of themselves such as a particular skill, their personal appearance or an assignment so when they're done they feel like a beautiful butterfly.
Person A: "Is Andrew coming to the party?"
Person B: "Nah he's cocooning."
Person A: "What for?"
Person B: "He's trying to get in shape."

Is like spooning, but when the little spoon is so small that they are totally wrapped and enveloped in their larger partners special hug that they appear to actually be in a cocoon.
She was so well covered in his flesh when spooning last night, she was actually cocooning.

Did you see that cute chick emerge from that hug?

That was not hugging, that was cocooning, and she was the butterfly.

The act of ejaculating so much onto a woman that she is completely covered in semen. In this sex practice, however, unlike bukkake the female will not clean herself off (She won't be able to if you're a real man, anyways) and will become wrapped in a 'Cocoon' of hardening cum, unable to move, or even breathe.

The male (Or Herm) will do this Solo and will repeat this process onto the cocooned victim as much as possible until the female is not visible.

Suggested to practice against walls, floors, or even ceilings (The last being most difficult. Like standing, the cum will drip downwards thanks to gravity and only a slight portion of her will be covered.)

The act of doing this to multiple persons is called Hive Cocooning
(A conversation about Cocooning)

Person A: "So, did you hook up with Cindy last night?"

Person B: "Hell yeah, man. I was saving up all month to Cocoon her."

Person A: "So?"

Person B: "Living room, left corner, I can't even see her anymore."
