Blanket pig means blanket hog meaning someone who hogs the blanket way too much by yanking it away leaving you shivering. A blankeg hog is usually a friend at a sleepover, spouse, or a relative you are sharing a bed with.

To cope with a blanket hog simply either yank the blanket back, get another blanket, get a sweater, move sleeping locations, or just shiver your ass al night.
