A euphemism for merconium. Immediately after a baby is born, the first few shits he makes is full of merconium which is nearly like messy, nasty, sticky, gooey tar. Thus, "silly putty".

Of British origin, often heard in British, Canadian, Australian and New Zealand army units whjen referring to someone who behaves stupidly while in combat. Sometimes the expression can also be used to refer to going off on exercises.
"Oh, look! The silly bugger has gone and gotten his arse shot off!" Or, when referring to going on an exercise, "It looks like it's time for us to go and play silly bugger again."
