intrusion shield 

What every single dude needs to wear when he goes out on the town at night. It comes in two models- stainless steel buns and plasma offender repulsion. Stainless steel lets people know you're well defended (and leaves your enemy with marks and bad dreams), while plasma offender repulsion lets you make sure the offender will never offend again.

After slipping on a package of cottage cheese, Steve was saved from mass absolute bangage by his stainless steel buns intrusion shield.

cranio-rectal intrusion 

A malady common to carbon-based life forms, cranio-rectal intrusion is also known as having your "head up your ass." As the size of any bureaucracy or institution grows, an exponential increase in the number of cases of "cranio-rectal intrusion" will also occur.

With no repercussions ever being suffered for not following the very laws it institutes, the U.S. Congress continues to prove that the people of the U.S. are suffering from a level of apathy that can only be achieved by prolonged cranio-rectal intrusion.
