A doodle is a type of sketch, an unfocused drawing made while a person's attention is otherwise occupied. Doodles are simple drawings that can have concrete representational meaning or may just be abstract shapes.
Stereotypical examples of doodling are found in school notebooks, often in the margins, drawn by students daydreaming or losing interest during class. Other common examples of doodling are produced during long telephone conversations if a pen and paper are available.
Is quite interesting because during my childhood days my doodle design was a series of squares within squares. And a human face with a crown on top. God knows what it actually meant but atleast now i have a term to describe or give a name to that behaviour.
