Also known as the radio's clean version of the word "motherfucker". This is typically created by the rapper/singer/whatever we're calling people on mainstream radio these days when they attempt to say "motherfucker" but instead only get to say "Muthaf-" before the producers say "No! We can't say that on the radio! There are very impressionable kids that listen to this thing some people call music!" and fade them out by distorting the track to say "oh" and making their voice go all into the nether regions of the musical notation system. This effect can also be used in the case that they just want to sound "edgy" without actually saying "moherfucker".
