When one is totally wasted on alcohol and/or drugs at a hotel, and walks right into a wall mounted light fixture (sconce) in the hallway. Knocking oneself out.
A type of female who is really hyper and sometimes somewhat annoying. A Sammer can automatically make any situation really awkward and she laughs at really inappropriate times. She drinks alot and loves to party, and when shes drunk she sometimes confesses her love for her bestfriends. People get tired of her really easily and usually like her alter-ego alot better.
