Who came up with the Euphemism Treadmill?
Stephen Pinker (2003)
What is the general concept of the Euphemism Treadmill?
Words which are introduced to replace existing offensive words over time become offensive themselves
Example of a euphemism treadmill:
Idiot > retarded > mentally challenged > special
Crippled > handicapped > disabled
What is a dysphemism treadmill?
It works in the opposite way as a euphemism treadmill, however this works in the opposite way as the word develops a slightly less offensive meaning
