mom rocket

A minivan that drives at extreme speeds and very recklessly through traffic, usually with an overly-stressed middle-aged suburban-dwelling mother of 4 kids that's running late to her 2nd son's soccer practice

Mike - "Did you see that Ford Windstar bobbing and weaving through traffic?"
Dan - "Yeah man, that was like a mom rocket!"
AJ - "She must be late to her kid's soccer practice."
