The "Germ Defense"

..a good offense is a good (germ) defense,.

There's a long-running cable TV show that often features a faux impersonation of the great defense attorney Johnny Cochran. in various gags. During faux-Johnny's arguments to the jury during the show, he often incorporates the "Chewbacca Defense", a long running spiel that incorporates no evidence or trial-related information, but sounds good and thus guarantees a victory for the attorney.

We have something similar. In education, it's called the "Germ-Defense". It doesn't always attack the real issue at hand, but sounds pretty dang good, so we use it anyway. Guaranteed to shock and awe when applied.

For example:

"Why did you sit in that urinal and flush it? Don't you know about all of the germs in there?!?!"

"Why did you try to kiss that boy under the table? Don't you realize how many germs are there?!?!"

"Why did you just put rock salt in your mouth and spit it at your school counselor? Don't you realize how many germs are on it?!!?"
