Purpose and FunctionTo aid memory.
What is a "Hissohathair?"
I do not know.
The origin of the name comes from some graffiti scrawled on a few walls in what was my home suburb of Enmore (Sydney, Australia). It was variously written as "hisso hathair", "his so hat hair", and "hiss ho hat hair."
I never did find out what that meant. But it was amusing (to me), unique (and therefore registrable) and opaque.
