In a battle of wit during discussion on public forums, message boards, fb groups.. etc. an Ivanism is considered to be a truly weak response of the highest degree. A weak and unbalanced retort in which extreme cases of butthurt are revealed. An Ivanism is also known as a euphemism to the expression "
foot in mouth" which in many cases may come back to haunt person (who in lost train of thought or just out of plain stupidity
blurts out said Ivanism) at a later time, even much later.
Some Ivanisms are so epic in content that they warrant being saved and stored for future/
educational purposes.
