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!

Get the dun-dun mug.
When a person can't get himself to talk about a certain ongoing subject (normally on chatrooms) and is put in a awkward situation, where some might expect a reaction from him and he goes,

"dun dun."

It comes from "so done with this". Usually related with Otaku culture for some reason.
Person 1: I just raped this bitch so fucking good, i swear i did.

Person 2: Hahaha so funny!
