More than just the opposite of exaggeration , an inaggeration is the removal of the colloquial interest which can be added to an otherwise boring sentence. To exaggerate would be to say you were paid a million dollars for a
job you got
10,000 for, an inaggeration would be to say anywhere between 9000 and 11000. It is not exactly a statement of
truth but it isn't incorrect enough to add anything to the
story. More extreme cases of inaggeration are known as Hypoboles.
Guy 1: '
Chuck Norris is so strong that he can lift an automobile.'
Guy 2: 'Nobody has said a Chuck Norris joke in 5 years and you expect to revive them with that hypobole piece of
shit. If you inaggerate once more i'm going to stick my foot so far up your ass that it
will hurt a little'
