When your head swells from drinking paper-bagged gas station liquor and it inflates like a balloon, while the rest of your body sheds all of its remaining muscle and you look like a stick figure otherwise.

You can visit a bag head removal specialist, but it's really expensive and no health insurance plan will cover the cost. You can also try mewing.
