everyone around them: DUN DUN DUUUUUUUNNNN!!!

dun dun dun

This usually occurs straight after what we call in guitaring terms, "the thunder chord". This is from the hit Slayer song which sounds like all the others, Raining Blood. After the initial dun dun duns there is another type of thunder which is simply called "pinch harmonic dm7 thunder creatarsm". Then the guitars come in with wee niddle nee niddle nee niddle nee. Of course the dun dun duns keep going throughout the song and so provide fantastic music listening

DUN DUN DUN! wee niddle nee niddle nee niddle nee DUN DUN DUN!

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.

Tits or gtfo. Dun dun.
