Expodentially is a slang word used at strategic points in a conversation or speech to avoid using the word “exponentially”, which means substantial. This tactic is commonly used by politicians who lack integrity, to avoid being caught in their lies when their promises ultimately turn out to be empty.
Politician: “ And if you vote for me, you’ll see the money in all of your bank accounts grow EXPODENTIALLY!”
Biden coined the term in one of his speeches for you know you know the thing, yah know that thing...?
"The dependant of the mask and the type you wear increases expodentially that if you are a carrier and don't know it you will not spread."(This was all I could decipher from Biden's speech before I gave up).
