A slightly less intense way of saying murder.

Dwight: "'R' is among the most menacing sounds. That's why they call it Murder, not Muckduck."

Expository. The reason 'Murder' sounds so hard is the R sound.

That's why it's called Murder not Muckduck.

muckluck

Bastardized form of the word "mukluk" which refers to a boot made from animal skin worn by Eskimos or boots of similar fashion. Yeah, this is the word Krusty uses in that particular Simpsons episode.

Krusty: Kent, the young people today, they think comedy is dirty words. It's not -- it's words that *sound* dirty, like "mukluk."

Just a swear word. Previously seen in the National Lampoon. A dirtier version of "fiddlesticks".

"Oh, fuckleducks."
