an annoying yet extremely entertaining exclamation used most efficiently with "your mom"s for the perfect burn.

everyone around them: DUN DUN DUUUUUUUNNNN!!!

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!
