It can be amusing at times when people mis-speak (hopefully it just mis-speaking) and you know what was intended to be said. I was told a story a few days ago about a young fellow who was concerned about a roommate doing things in their apartment. The details are not important, but the term "contraseptic" (as a noun) was used in the original

contra = against
septic = an infection, or a method of sewage disposal, or Cockney rhyming slang for American, or a polynomial of degree seven

So you would have to be against infected American mathematicians who have sewage trouble.

Oh no, we do everything naturally at the cabin -we have an outhouse and only use water, leaves and squirrels for wiping delicates. You could say we're real Contraseptics"

Or a radical Contra group-
"Dude, we wear jack boots and movement is free we are Contra, Contra SEPTIC!
*throws horns*"

Contraseptic - The last line of defense against the sort of people who use the word 'contraseptic' in place of CONTRACEPTIVE.

Like antiseptic, but more guerrilla.
