When someone makes up a word that looks like an English word and can be readily
spelled, the rule is that the word should be quoted. There is no need to use after
such a word. The quotes clue the reader that something is unusual about the word.
...It was "dramastically" reduced in size.
...There was always "insinuendo" about his status.
...I think her behavior was just "redunculous."
Happy punctuating!
