An American expression used during WWII, typically seen in graffiti. Not much is known about its origin but the phrase and the doodle became associated with GIs in the 1940s. It was also the American equivalent of the Australian Foo Was Here expression that was used during WWI. It mainly features a bald-headed man (sometimes depicted with a few hairs on his head) with a prominent nose peeking over a wall with his fingers clutching the wall. Despite this, his name is not Kilroy (there were many different names for the character such as Smoe, Clem, Flywheel, Private Snoops, Overby, The Jeep and Sapo).
