My girlfriend had someone tooting and swearing behind her one day, when she was waiting to turn onto a busy highway. So got out of the car, tottered up to the guys behind, in her high heels, car full of guys yelling abuse. After an exchange or two, she told them to "fuck off" and watched their jaws drop. Then turned onto the busy road, and drove slowly down the middle, straddling the two lanes, so they couldn't get past.
