How many times do you wipe?

From the film:

"A fighting man must be vigilant to surprise attack no matter where he is. The survival of our nation depends on the readiness of Marines all over the world. Also more importantly, you only wiped yourself twice - grossly insufficient. Right now, germs with names you can't even pronounce are preparing to launch a devastating attack that will render you helpless in the defense of your country... Do you read me?"

Is two insufficient? I really want to understand.
