I am interested in your name 'oxymore' what does it stand for?
Oxymorons are sometimes inadvertently created by errors or sloppiness in conversation; common examples include
extremely average,
objective opinion, and
original copy. In some cases an inadvertent oxymoron ends up being widely adopted as the name for some concept and ceases to be recognised as an oxymoron. Cases where this has occurred include
bittersweet,
virtual reality,
constant variable, and
living dead.[
