Put the pedal to the metal and crash right into his rear

You decide to teach the nerd a lesson by ramming him in the rear. The impact doesn't do your front end any good, but you don't care. The nerd swerves off the road and comes to a stop. You laugh at the sight of him sticking his hand out the window to give you the finger as you breeze past him.

You look again in your rear-view mirror and realize that the nerd looks somewhat... effeminate. That's a nerd girl that you just drove off the road.
