                            When you roll a two in craps, it is called 'Snake Eyes' - eyes because they look like eyes, snake because they are bad news (for the shooter).
                                                            
                                                     
                        
                                                
                        
                        
                            In gambling, snake eyes is the outcome of rolling the dice in a game of craps and getting only one pip on each die. The pair of pips resembles a pair of eyes, which is appended to the term 'snake' because of the long-standing association of this word with treachery and betrayal. The dictionary of etymology traces that use of the term back to 1929http://www.etymonline.com/index.php?l=s&p=28 Online Etymology Dictionary, although it may be traced all the way back to the ancient Roman dice games, where 'Dogs' represented two ones.
