(n.) Strombone: A pretty awesome individual on twitter who may or may not be gold-medal winning, excessively criticized and all-around awesome goaltender, Roberto Luongo. Generally enjoys self-deprecating humour, poop jokes and may have a secret crush on Snooki. Also tries very hard to get other hockey players to follow him. When Strombone tweets, the twitters soon.
