Flannel. I hate the word “flannel” it's rank.
Curling. A friend of mine uses the minging term “Curling one out”
Banger. Used more commonly to describe a good song. “Absolute BANGER” sounds gross.
Taking a shit / took a shit. I hate that phrase. “Dogs have been out – took a massive shit right in the road”
One of my favourite words is “Confabulation” which sounds like a really offensive swear word you'd call someone with venom as in “You confabulating BASTARD”
I genuinely want to know what perfectly normal words or phrases make you wince and cover your ears.
