I am just as likely as DH to use an anodyne irritant word like 'squawking'. Nothing to do with control, all to do with what words all of us use when irritated.
There are far worse words, like 'c*nt. wh*re, and the full gamut of really vile and obscene words contained within the English language, 'squawking' isn't even an expletive!
I refuse to believe that everyone obecting to this word live in perfect relationships, where never a bad word is used, no one ever disagrees. All of us get irritated at times and use perfectly clean normal words but with an inflection or tone that makes them mildly pejorative.
I would include 'squawking' among these normal words that can be mildly perjorative in the wrong context. Parrots squawk, so, do other birds. All kinds of sounds can be described as squawking.
Lats face it, said with the right tone of voice the word 'darling', 'love', or 'sweetheart' can be an insult.
