Alternative name for any crossover style SUV, typically driven by mommies (and daddies) for "practicality" despite being no bigger than a car while driving worse, getting worse fuel economy, and costing more.

Alternatively, it is also driven people so insecure by their driving they worry about surviving when they hit someone else due to their incompetence.
