Minivan Complex

A seemingly uncontrollable urge to prevent minivans from overtaking another vehicle due to the amount of shame and embarrassment it would bring.

"I was driving to work today and a van had the audacity to drive faster than me! Can you believe that? I'm not gonna let some stupid soccer-mom minivan overtake me!"
"Dude, it sounds like you have a minivan complex."

"I was trying to get ahead of this slower-moving car but for some reason every time I tried he would speed up and cut me off!"
"Sounds like he had a pretty big minivan complex."
