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."
