Huh? Never heard of the term mouth-breeders (brooders) being used outside of the realm of aquatic biology. 'Mouth-breather' is the properly-used slang calumniation meaning a stupid person, imbecile, moron, etc. The older term is 'slack-jawed'; both terms reference the impression that holding one's mouth open makes one appear less intelligent. It's also a potentially serious medical condition.

The use of the word [mouth-breather] as an insult, based on the idea of the dopey expression of someone with their jaw hanging open, and possibly the nasal sound of their voice, actually dates as far back as the 1940s, but has recently emerged from obscurity through use on the Web, especially in the US, where it has also been used on television and by the popular press.

By the way, the term 'denigration' might be considered by liberal mouthbreathers to be racist. It literally means 'to make black'. LOL!
