Knifey Spoony is the name of an Australian game of comparing the length of knife blades, with the longer one winning.
A player may also produce a spoon, that – if not identified by the opponent – beats the knife. However, if the spoon is noticed to be a spoon, then the person producing it loses.
The name comes from the season 6 episode 16 of Simpsons, in which Bart goes to Australia and gets a pocket knife to carve his name on the bar table, to which a local approaches him with a spoon.
The scene is a reference to the 1986 comedy, Crocodile Dundee where the protagonist is almost mugged, but intimidates the robber with a massive hunting knife.
