One who dissapears or acts as if he/she is sly, or does sneaky things without peers knowing. Usaully when a person is a Secret Squirrel, that person acts scary as if someone is on to them or, knows whatever the secret might be. This word comes from an Hanna-Babera created cartoon, which tells about a
detective/spy Squirrel who jumps around hiding and solving
mysteries. My dad also likes to call my
older sister and my mother a Secret Squirrel often when playing aorund with them.
