A suffix used to make a word, symbol, or abbreviation that isn't normally a verb into a past participle. This is a common way to verbalize something ending with punctuation or to make clear which part is the root and which is the suffix. Examples: instead of saying "You were 2fered," which looks weird, you would say "you were 2fer'd." Also, "Yes, I've NFN'd" instead of "I've NFNed."
