Bedhead

When after a long drinking binge, you miscalculate the distance between yourself and the headboard, and flop backwards only catch enough headboard to crack the back of your skull. Thanks to the alcohol or drugs involved in this faux pas, most sufferers only feel the true effects of bedhead when they awake to a large awkward lump on the back of their head. A common reaction of the bedheadee is to pick up the phone and bitch at whomever they were out with the previous night for allowing them to get their asses kicked. While it's a sadly mistaken first notion, the victims of bedhead are, of course, not thinking clearly.
