fake swearing
Consequence-free rudeness. Extending the ring finger, or making V-signs with the middle and ring fingers, will cause initial shock and offence, but when it is pointed out which fingers you are using, the parent or teacher will find themselves impotent in the face of your devilish wit. That's how it's supposed to work, at least.

Sheet Head (better),
Mother Fudder (acceptable).

I'm sure everyone who had been forced to learn Latin at my school knew that they had free reign to scream "Fac id!" and then be left to try to explain to a teacher how actually they were demonstrating their dedication to their schoolwork by practicing irregular imperitives in their spare time.
