Dun Dun Dun
Used immediately after a shock revelation, in the style of a 1940's or 50's movie.
an annoying yet extremely entertaining exclamation used most efficiently with "your mom"s for the perfect burn.
always following a question regarding the statement in the format of:
or *insert verb* *insert pronoun*?!
person 1: I had fun with your mom last night.
person 2: or did you?!
everyone around them: DUN DUN DUUUUUUUNNNN!!!

Dun Dun
The sound between scenes in Law and Order. The expression originated when 4chan changed the "Post Successful" page and font to look like the Law and Order black screen between scenes. The page played the sound, "Dun Dun," from Law and Order. 4chan /b/tards began to post the expression, "Dun Dun," anywhere to import a sense of finality or just randomly.
The process of attempting to steal action from someone else's post where the original poster is specifically looking to make a bet. Often occurs in social media but is always in poor taste. Named after the original individual who has since learned proper etiquette.
Dominick was always dunning on Mike's post trying to steal the action Mike was looking for.
