Euphemism Treadmill

A euphemism is a term or a phrase used by individuals to refer to a controversial topic as overwhelmingly inoffensive as possible, as opposed to being politically incorrect (aka "enthusiastically offensive").

Unfortunately, the overuse of a euphemism will eventually devolve its meaning to the extent that itself becomes politically incorrect and will have to be replaced with another euphemism. This is a sociolinguistic phenomenon to as the "euphemism treadmill".

The term "mental retardation" was once a euphemism and politically correct term used to describe stupidity. The previous term was imbecile which was an actual medical category which comprised of idiots (IQ 0 to 25), imbeciles (IQ 26 to 50), and morons (IQ 51 to 70).

Over time, mental retardation and its associated verb "retard" became as corrupted as "imbecile" and "idiot" and was eventually replaced with "intellectual disability". It is now only a matter of time when being "disabled" is offensive and once again, slides down the euphemism treadmill.

euphemism treadmill

The process by which a pejorative term is replaced by a more politically correct term, only to over time be corrupted and used pejoratively itself until a new term is introduced, upon which the cycle repeats itself.

So named because walking on a treadmill gives you the illusion of going somewhere, when actually not making any progress. Basically a form of political correctness masturbation.

The best example of a euphemism treadmill is the word "retarded", which was originally adopted as a more apt and kinder alternative to previous medical terms such as "moron", "imbecile", and "idiot".

"Retarded" is currently considered a pejorative insult, so new terms have been invented such as "special needs" and "intellectualy disabled" , which will in time become pejorative insults themselves. Thus retarded SJW's, downie parents, and the self-righteous will always have something to bitch about.

treadmilk 

treadmilk is created when sweat from the person on the treadmill mixes with their foot grease, and gets caught in the treadmill. Later, it is then turned to sludge,{which is the treadmilk} and once consumed it creates a healthy diet of treadmilk which is incredibly healthy!

Guy 1: *phew!* it takes me forever to get slim with these regular diet drinks.
Guy 2: well that's why i used treadmilk!
{PS don't actually try this}

Canadian Treadmill 

It's a euphemism for putting maple syrup on someone while massaging doggy style in an Ice hockey suit. It's what all the kids are about these days.

/r/Peejwal: "Canadian Treadmill? Sounds like a sexual Urban Dictionary term."
/r/SouthFM: "It is now."

Swiss Treadmill 

This is the female version of the Dutch Rudder. A Swiss Treadmill is when one female assists another in masturbation by grabbing the partners arm and completing group masturbation.

I saw that video of your girlfriend and her mom Swiss Treadmilling on the internet!
